Question

construct a triangle ABC in which angle A is equal to 40 and c is 80 and xy + y z +zx=12

Answer 1

Step-by-step explanation:

draw a line segment pq=12cm

at p construct angle of 60° and q, an of 45°

bisect these angles

Answer 2

ΔABC is Constructed with ∠A = 40° & ∠C = 80° and perimeter = 12 cm

Step-by-step explanation:

Step 1 : Draw  a line segment XY  = 12 cm

Step 2 : Make an angle of 40 ° at X on XY using protector

Step 3 : Make an angle of 80° at Y on XY using protector

Step 4 : Draw angle bisector of 60°  & 30° and let then intersect at B

Step 5 : Draw perpendicular bisector of BX  & BY and let them intersect XY at A  & C

ΔABC is required triangle

∠A = 40° & ∠C = 80° and perimeter = 12 cm
