Construct a trian

We have been given two sides and one angle of triangle LMN.

Steps of construction for this case would be:

1. Draw a line segment sufficiently long using a ruler.

2. Locate points M and N such that MN = 6.3 cm.

3. At M, construct a line segment MX, sufficiently large, such that ∠XMN = 45°; use protractor to measure the angle 45°.

4. With M as centre and radius 7.8 cm, draw a circle or a semicircle or an arc cutting the line segment MX at L using a compass.

5. Join LN.

Thus, LMN is the required triangle.
