In this video lesson, we learn about similar figures and indirect measurement. The teacher explains how to identify similar figures, find missing side lengths using proportional ratios, and use angle-angle similarity to solve problems....

👉 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...

In this video, the concept of similarity between circles is explained using the concept of similar triangles. It demonstrates how to determine if two circles with different radii are similar by examining the corresponding angles and...

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

In this video, the teacher explains how to find the different lines of symmetry in a geometric figure. They discuss the three types of lines that can determine the symmetry of a figure: horizontal, vertical, and diagonal.

In This Episode, Tyler Teaches Us About The Area of a Regular Square Polygon WHAT!!!

👉 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...

This lesson and practice will review the steps using an organized list to find the area of composite figures. Students will learn that a composite figure is two or more two-dimensional shapes. Finding the area of each shape and adding...

This video explains the properties of an isosceles triangle and helps viewers answer a standardized math test question about it. The teacher breaks down each answer choice and shows how to arrive at the correct answer.

In this video, the teacher explains the basics of triangles, including the interior and exterior angles. The lesson covers the triangle sum theorem, using ratios to find angle measures, and the exterior angle theorem. The teacher...

Classifying polygons based on the presence or absence of parallel lines.

In this short video we will answer a standardized math test question where we are asked to identify a missing angle of a triangle. We will review the definition and meaning of similar triangles. We will identify which angle corresponds...
