. .(write steps ​

Answer 1

Answer:

plz make me brainlist

Step-by-step explanation:

Construct an isosceles A ABC such that:

(i) base BC = 4 cm and base angle = 30°

(ii) base AB = 6-2 cm and base angle = 45°

(iii) base AC = 5 cm and base angle = 75°.

Measure the other two sides of the triangle.

Answer 2

Construct an isosceles ∆ABC such that:

(i) AB = AC = 6.5 cm and ∠A = 60°

(ii) One of the equal sides = 6 cm and vertex angle = 45°. Measure the base angles.

(iii) BC = AB = 5-8 cm and ZB = 30°. Measure ∠A and ∠C.
