👉 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 identify the attributes of shapes by using their classifications. The focus is on shapes that have exactly two pairs of congruent sides. The teacher provides examples of shapes like...

👉 Learn how to find the corresponding pairs of congruent triangles. Two or more triangles are said to be congruent if they have the same shape and size. To determine the corresponding congruent parts of a triangle, we use the congruent...

👉 Learn how to solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a...

In This Episode, Tyler Teaches Us About Congruent Shapes

In this video, students learn about the properties of congruence and how to determine if two figures are congruent using reflections. The video explains the concept of reflections, including how size and shape stay the same while...

In this video lesson, students learn how to find the area of a right triangle by composing a rectangle. The teacher explains the concept of a right triangle being half of a rectangle and demonstrates how to find the area of a triangle by...

The video explains the different criteria or conditions that can be used to prove that two triangles are congruent or identical to each other. The speaker discusses four different rules: side side side, two sides and the included angle,...

In this video we will present and prove our first two theorems in geometry. Right angles theorem and Straight angles theorem.

👉 Learn how to find the corresponding pairs of congruent triangles. Two or more triangles are said to be congruent if they have the same shape and size. To determine the corresponding congruent parts of a triangle, we use the congruent...

ACT SAT Prep How to determine the length of a parallelogram given a side and perimeter

The attributes of a rectangle include having four right angles, two pairs of parallel lines, and opposite sides that are congruent. This video provides examples and explains why certain shapes do or do not belong in the Rectangle Room at...

👉 Learn about congruent triangles theorems. Two or more triangles are said to be congruent if they have the same shape and size. There are many methods to determine whether two triangles are congruent. Some of the methods include: (1)...

It explains the criteria of congruence such as SSS, SAS and ASA. It also states the conditions for proving two right-angled triangles to be congruent.

In this video, the teacher explains how to determine if two figures are similar by using rigid transformations and dilations. They discuss the different types of rigid transformations, such as translation, reflection, and rotation, as...

In this video, the teacher explains the concept of tangents to a circle and their relationship with the radius. The teacher proves the theorem that a tangent line is perpendicular to the radius at the point of tangency. Additionally, the...
