FIGURE IT OUT

3. Construct a right-angled triangle ∆ABC with ∠B = 90°, AC = 5 cm. How many different triangles exist with these measurements?
[Hint: Note that the other measurements can take any values. Take AC as the base. What values can ∠A and ∠C take so that the other angle is 90°?]

4. Through construction, explore if it is possible to construct an equilateral triangle that is
(i) right-angled
(ii) obtuse-angled.
Also construct an isosceles triangle that is
(i) right-angled
(ii) obtuse-angled.
