Question

Construct a right angled $△ABC$ with $\angle B={90}^{\circ },BC=5cm$ and $AC=10cm$ and find the measure of $\angle C$ in degrees

Answer 1

Step 1. Draw a line segment $BC=5cm$

Step 2. At $B$ draw an angle of ${90}^{\circ }$ and extend the ray.

Step 3. Now taking $C$ and centre draw an arc of radius $10$ cm intersecting the previous ray at $A$.

Step 4. Join $C$ to $A$.

Now using a protractor measure $\angle C$

$\angle C={60}^{\circ }$
