Question

Construct a triangle who perimeter is 15cm and its two base angle of and 30.

Answer 1

Steps of construction
STEP1: Draw DE of 15 cm.
STEP2: Draw EDP =∠ B = 30° and ∠ DER = ∠C = 30°
STEP3: Draw the angle bisectors of ∠ EDP and ∠ DER and mark their point of intersection as A.
STEP4: Draw the perpendicular bisectors of AD and AE. They meet DE at point B and Point C respectively.
STEP5: Draw AB and AC to get the required triangle ABC.
