Mr. Addit defines the terms; right triangle, hypotenuse, legs, equilateral, equiangular, isosceles, scalene, equiangular, obtuse, and acute.

Mr. Addit reviews geometry fundamentals including: points, lines, line segments, rays, perpendicular and parallel lines, acute, obtuse, and right angles, and isosceles, scalene, and equilateral triangles. He also reviews polygons...

In this math video we will learn how to draw an isosceles triangle in a coordinate plane. We will be given three important fact about a triangle to construct a triangle in the given coordinate plane. We will first understand how to...

In this math video we will determine how many unique triangles can be formed from a proposed list of angle measures. We will begin by reviewing the Triangle Angle Theorem which states that the three interior angles of a triangle must...

In this math video we will learn about congruent triangles & their angle measures. We will review the definition of congruent figures which is that congruent figures have corresponding sides and corresponding angles that are congruent....

In this video we will explore how to find the missing measure of a triangle using the properties of triangles like when we have an equilateral and isosceles triangle.



⭐️ Review of Right Triangles -...

Area: Isosceles Triangle finds the area of an isosceles triangle by using a T chart to describe both the mathematical operations and the written explanations.

“Let’s Talk about Triangles” describes the main types of triangles and explains what makes each type unique.

Classifying Triangles explores the six types of triangles by defining the triangle types and classifying triangles by side length and angle measurement.

This video explores five fun facts about triangles.

In this series of programs students are introduced to perimeter and area. Easy-to-understand examples enable students to understand the process by which perimeter is calculated. The area of rectangles, parallelograms, and triangles is...

👉 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...
