Thank you ! Thank you ! This is an amazing resource. The step by step lessons make it simple to learn the concept. All Things Algebra is my go to resource for all my algebra needs!!!
The units and videos are amazing. I use ATA's Geometry units for outside tutoring with a few students. I used them to help refresh myself, but also the students found the videos and extra practice problems super helpful! I cannot say enough good things about all of the units.

All Things Algebra has become my go to. This unit, among many others, is well structured and extremely well organized. I found this unit to be especially helpful because of the way the guided notes were organized for the triangle congruence and proofs. It can be a dry unit, but the way it is set up makes all the difference. Thank you!

In EFG, the legs are segments EG and EF. The third side is called the base. In EFG, the base is segment GF. The angles on either side of the base are called base angles. In EFG, the base angles are <G and <F. The angle opposite the base is called the vertex angle. In EFG, the vertex angle is <E. Unit 4 - Congruent Triangles Lesson 1: Types of ...
In geometry, two triangles are said to be congruent if they are the same size and shape.This means that all corresponding angles and sides are equal.. To prove that two triangles are congruent, we must use one of the five congruency tests: Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL).The SSS test states that if all three ...
congruence (pay attention to proper correspondence when naming the triangles) and then identify the Theorem or Postulate (SSS, SAS, ASA, AAS, HL) that would be used to prove the triangles congruent. If the triangles cannot be proven congruent, state "not possible." 28) 29) Given: CD ≅ AB; ∠B ≅ ∠D Given: JN ≅ LM; NK ≅ MK;
In other words, if = 5, = 7 and = 7, you can tell angle C is the smallest angle and angles A and B are congruent. AIM: To classify triangles by angles. To define the "sum of the angles" of a triangle. To solve problems involving the angles of a triangle.

A triangle with three congruent sides. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two nonadjacent interior angles. The points that are the intersections of the sides. Each point by itself is called a vertex. A triangle with one angle that is greater than 90 degrees.
The triangle congruence criteria are Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA) and Hypotenuse-Leg (HL). The first criterion for triangle congruence is the Side-Side-Side (SSS) criterion. This states that if the three sides of one triangle are equal in length to the three sides of another triangle, then the two triangles are congruent.
In this case, two triangles are congruent if they've exactly the same three sides and exactly the same three angles. The three rules for congruent triangles include: The three sides are equal (SSS). Two angles are the same and the corresponding side is also the same. (ASA). Two sides are equal and the angle between them is equal (SAS).
