Mathematics MCQs

An isosceles triangle has two equal sides.

Bisecting 60° gives 30°.

Drawing arcs from the point that intersect the line helps in constructing the perpendicular.

The right angle is 90°, so the base angles are (180°-90°)/2 = 45° each.

An equilateral triangle has all angles 60°, so it cannot be obtuse.

The perpendicular bisector intersects the segment at its midpoint.

Two arcs are used: one from the initial point and one from the intersection.

An obtuse-angled triangle has one angle > 90°.

Two angles only are not sufficient; the side must be specified.

Bisecting 90° gives 45°.
