Question

If a triangle is an isosceles then its will be congruent​

Answer 1

Step-by-step explanation:

If two sides of a triangle are congruent , then the angles opposite to these sides are congruent.

∠P≅∠Q

Proof:

Let S be the midpoint of PQ¯¯¯¯¯ .

Join R and S .

Since S is the midpoint of PQ¯¯¯¯¯ , PS¯¯¯¯¯≅QS¯¯¯¯¯ .

By Reflexive Property ,

RS¯¯¯¯¯≅RS¯¯¯¯¯

It is given that PR¯¯¯¯¯≅RQ¯¯¯¯¯

Therefore, by SSS ,

ΔPRS≅ΔQRS

Since corresponding parts of congruent triangles are congruent,

∠P≅∠Q

The converse of the Isosceles Triangle Theorem is also true.

If two angles of a triangle are congruent, then the sides opposite those angles are congruent.

If ∠A≅∠B , then AC¯¯¯¯¯≅BC¯¯¯¯¯ .

Answer 2

Answer:

heyy

Step-by-step explanation:

its not necessary,

first congruence we need two triangles and atleast one side must be equal

in your given question things are not specified

ask again with specifications

all the best for your future..
