Question

Contruct Triangle ABC such that angle A = 45°, angle B = 55° and AC = 4.5cm​

Answer 1

Step-by-step explanation:

Steps of construction

1. Draw a line segment XY.

2. Take a point M on XY.

3. Draw ZM⊥XY, with MZ sufficiently large.

4. With M as center and radius 3.6cm, draw an arc, cutting MZ at A.

5. With A as center and radii 4.5cm and 5cm, draw arcs cutting XY at B and C respectively; join AB and AC.

Then ABC is the required triangle.
