Question

∆ABC is an isosceles triangle with AngleA= AngleB=70%. Identify the pair of sides which are equal.​

Answer 1

Answer:

40

Step-by-step explanation:

Given, AB = AC, ∠B=70

∠B=∠C=70  

  (Isosceles triangle property)

Sum of angles,

∠A+∠B+∠C=180

∠A+70+70=180

∠A=40

Answer 2

Answer:

70,40

Step-by-step explanation:

The Step 1 is angle A =Angle B so angle A is 70 than than the angle B us also 70 because it is an isoceles triangle.

the Step 2 is Angle sum property

than 70+70=140

180-140=40

so the all sides of triangle are 70 ,70,40

Verification

Sum of all angles of the triangle is equal to 180°.

so 70+80+49=180°
