Q1 of 805 Page 12

Is it possible to construct a in which BC = 5 cm,
A. Yes B. No

Any triangle can be constructed with any value of two angles and length of the side included within them.

As can be seen from the figure, it is obviously possible to construct any ∆ABC with given two angles and the side included with them.

So, the correct option is (A)

Construct a triangle whose perimeter is 6.4 cm, and angles at the base are 60° and 45°.

Using ruler and compasses only, construct a Δ ABC from the following data :

AB+BC+CA=12 cm, ∠B = 45° and ∠C = 60°.

Is it possible to construct a in which AB = 5 cm, BC = 5 cm and AC = 10 cm?

A. Yes B. No

Is it possible to construct an angle of 75° using ruler and compass only?

A. Yes B. No
