Question

Construct a triangle with perimeter 10 cm and each base angle is 45 degree
​

Answer 1

Answer:

1.Draw a line segment, say XY equal to BC + CA + AB = 10 cm.

2.Make angles LXY equal to 45° and MYX equal to 45°

3.Bisect ∠LXY and ∠MYX. Let these bisectors intersect at a point A.

4.Draw perpendicular bisectors PQ of AX and RS of AY.

5.Let PQ intersect XY at B and RS intersect XY at C. Join AB and AC.

Answer 2

Answer:

Draw a line segment, say XY equal to BC + CA + AB = 10 cm.

Make angles LXY equal to 45° and MYX equal to 45°

Bisect ∠LXY and ∠MYX. Let these bisectors intersect at a point A.

Draw perpendicular bisectors PQ of AX and RS of AY.

Let PQ intersect XY at B and RS intersect XY at C. Join AB and AC.
