Question

what are all the theorems of triangles class 10​

Answer 1

Answer:

Theorem 1: The sum of all the three interior angles of a triangle is 180 degrees. Theorem 2: The base angles of an isosceles triangle are congruent. ... Where ∠B and ∠C are the base angles. Theorem 3: The measure of the exterior angle of a triangle is equal to the sum of the corresponding interior angles.

Answer 2

Answer:

There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.

1. SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. ...
2. SAS (side, angle, side) ...
3. ASA (angle, side, angle) ...
4. AAS (angle, angle, side) ...
5. HL (hypotenuse, leg)
