Explanation:

Question 46

Step1: Recall triangle types

A right triangle has one \(90^\circ\) angle, obtuse has one \(>90^\circ\), acute has all \(<90^\circ\).

Step2: Analyze given angles

The triangle has a \(90^\circ\) angle. So it's a right triangle.

Step1: Recall triangle types by sides

Isosceles: 2 equal sides, equilateral: 3 equal, scalene: all different.

Step2: Analyze given sides

Sides are 13, 14, 16 (all different). So it's scalene.

Answer:

a) right
