👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, cosine, tangent, cotangent, secant, and cosecant when given the sides of a triangle. If we have missing sides we...

In this video lesson, students learn how to use right triangles and angles of elevation and depression to find the height of a space shuttle on a launch pad. The lesson explains the concept of mathematical modeling and guides students...

👉 Learn how to find the volume and the surface area of a prism. A prism is a 3-dimensional object having congruent polygons as its bases and the bases are joined by a set of parallelograms. A prism derives its name from the shape of its...

In this video, students learn how to describe the cross-sections of a right rectangular pyramid by slicing at different angles. They are introduced to the concept of cross-sections and how they result from cutting a 3-dimensional shape...

In this video, the teacher explains how to find missing measures in triangles using congruence and similarity criteria. They cover different congruence criteria, such as side-side-side and angle-side-angle, as well as similarity criteria...

👉 Learn how to prove that two triangles are congruent. Two or more triangles are said to be congruent if they have the same shape and size. There are many postulates and theorems to determine whether two triangles are congruent. They...

In this video, students learn how to find the rules and the 9th step in a geometric triangle growth pattern using a table. The teacher explains the concept of steps and rules in patterns, and demonstrates how to identify the number of...

In this video, the teacher explains how to draw a hexagon by connecting six straight sides. The lesson emphasizes the importance of following three rules: drawing six sides, ensuring the sides are straight, and making sure all sides meet...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow steps. This video...

In this lesson, students will learn how to prove the Pythagorean theorem using similarity. By investigating and following a series of steps, they will discover that by cutting a right triangle and drawing altitudes, they can create...

In this video we are going to look at exterior angles of polygons. Exterior angles are a little strange. They make a straight line with the interior angle, rather than being the whole outside angle. There are a few different ways to...

👉 Learn how to evaluate an expression with the composition of a function and a function inverse. Just like every other mathematical operation, when given a composition of a trigonometric function and an inverse trigonometric function,...

👉 Learn about the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle intersects the x-...

👉 Learn how to solve problems with kites. A kite is a four-sided shape (quadrilateral) with two equal pairs of adjacent sides and the diagonals are perpendicular. Some of the properties of kites are: each pair of adjacent sides are...

In this video, the teacher explains the concept of tangents in a circle. They discuss the origin of the term, the point of contact, the number of tangents a circle can have, and various properties of tangents including their relationship...

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you need...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

In this video, the teacher explains how to use the measures of interior angles in triangles to find unknown angle measures. The teacher reviews the concept that the interior angles of a triangle add up to 180 degrees and that consecutive...

In this video, students will learn about the concept of angles and how they determine the classification of a triangle. The video explains the different types of triangles, such as acute, obtuse, isosceles, equilateral, and scalene,...

The video is a math lesson taught by a teacher who explains the properties of triangles and parallelograms when combined with parallel lines. The teacher uses real-life examples to illustrate the concepts and provides step-by-step...

👉 Learn how to evaluate the six trigonometric functions given a right triangle. A right triangle is a triangle with 90 degrees as one of its angles. A right triangle is made up of two legs, which formed the sides of the 90 degrees angle...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow steps. This video...

👉 Learn how to evaluate the secant of the sum or difference of two angles using the sum/difference formulas. To do this, we first use the Pythagoras theorem to obtain all the sides of the right triangle in the unit circle. Recall that...
