Question

5) Construct an isosceles triangle with each of equal sides of length 5 cm and the angle between them is 75°

6) Construct a triangle LMN in which LM = 4.2cm, MN = 5.8cm and angle M = 80°

7) Construct an isosceles triangle ABC in which AB = AC = 5.5 cm and angle B = 35°.​

Answer 1

Step-by-step explanation:

5) take 5 cm as base. draw a line AB of 5 cm. construct 75° at B with protractor or compass ( for compass construct 90° and then make angle bisector between 90° and 60°).

extend the line and cut at 5 cm. mark C

join AC

6)

• draw LM = 4.2 cm
• draw 80° at M
• extend M and cut at 5.8 cm
• mark N
• join LM

7)

• same as 5) but changing the values
