Mathematics MCQs

An acute-angled triangle has all angles < 90°.

The perpendicular distance between parallel lines is the shortest.

Bisecting a 60° angle gives 30°.

Using Pythagoras: √(3²+4²)=5 cm.

A 45°-45°-90° triangle has two equal sides and a right angle.

Compass and ruler are used to copy an angle accurately.

In an isosceles triangle, the base angles are equal.

Each interior is 60°, so exterior is 180°-60°=120°.

Each side has a perpendicular bisector, so three.

The circumcenter is the intersection of perpendicular bisectors.
