Question

10. Construct a AABC in which AB = 7 cm, ZA = 45° and ZC = 75°.
​

Answer 1

Answer:

steps of construction -

1. first draw a line segment AB=7cm

2.then with A as centre construct angle A =45°.

[in triangle ABC

you are given that A=45° and C=75°

so by angle sum property-

45+75+B=180

B=180-120

B=60°]

3.now with B as center construct angle B=60°

4.mark the point of intersection of Angle A and B as C.

thus ABC is the required triangle.
