Question

Construct an isosceles triangle whose altitude is 5 cm and whose vertex angle is 70°.

Answer 1

see ur NCERT Book if u do not understand then I will tell u

Answer 2

Construction steps :

1 ) Draw a line XY .

2 ) Take any point on D on line XY

and draw DE perticular to XY .

3 ) Take D as a center and radius 5cm

( Given altitude 5 cm ) draw an arc that

intersect DE at A .

4 ) Mark points B and C on XY such

that <DAB = 70°/2 = 35°

and

<DAC = 70°/2 = 35°

Required Isosceles triangle with

altitude 5 cm and vertex angle 70°

is formed.
