Question

A triangle can be constructed if the measure of two angle and side is given

• A. included
• B. non-included
• C. adjacent
• D. opposite

Answer 1

The correct option is A included

A triangle can be constructed if the measurement of two angles and included side is given by marking respective angles at the included side and drawing lines through these marks. The point where these two lines intersects becomes the third vertex of the triangle.

For example:


As shown above, $\Delta$ ABC is constructed from the measurement of two angles of $\angle$A = 70${}^{\circ }$ and $\angle$B = 50${}^{\circ }$ with the included side AB being 4 cm.
