Overview
This article is about proving the congruence of two triangles given a figure composed of 2 triangles. It discusses different methods and postulates to prove congruency, such as angle-angle-side, side-side-side, angle-side angle etc. The article also provides examples and explanations for each method.
Triangle Congruence
Given a figure composed of 2 triangles, prove that the triangles are congruent or determine that there's not enough information to tell.
Differences in Postulates
The difference between angle-angle-side and angle-side-angle postulates is discussed.
SAS Postulate
It is explained why you cannot use the two congruent sides of AB and DC to use the side-angle-side postulate.

How do you prove triangles are congruent?

The hypotenuse leg theorem is a criterion used to prove whether a given set of right triangles are congruent. The hypotenuse leg (HL) theorem states that; a given set of triangles are congruent if the corresponding lengths of their hypotenuse and one leg are equal.

How do you calculate the angles of a triangle?

Answer: The angles of a triangle add up to 180 degrees. An interior angle is an angle measured between the two sides of a polygon. Using the general formula for the sum of the angles of any polygon S = (n - 2) × 180. Thus, the angles of a triangle add up to 180 degrees.

How do you use a triangle calculator?

Triangle calculator: simply input 1 side length + any 2 other values, and TrigCalc’s calculator returns missing values in exact value and decimal form – in addition to the step-by-step calculation process for each missing value. Trigonometry students and teachers, see more math tools & resources below!

What is the sum of the angles in a triangle?

The sum of angles in a triangle are 180, and if you have an iscoseles triangle, the angles opposite the congruent sides are congruent also. So if you have x as one of the angles opposite and a vertex angle of x + 30, the other opposite angle is also x, so x + x + x+ 30 = 180 which you can solve.
