Question
Construct triangle ABC, when: AB = BC = 5 cm and AC = 3 cm. Measure angles A and C. Is ∠A = ∠C?
Solution
Steps of Construction:
(1) Draw a line AB = 5 cm.
(2) Using compasses and taking B as center, draw an arc of 5 cm radius.
(3) With A as a center, draw an arc of 3 cm radius, which cuts the previous arc at C.
(4) Join AC and BC.
