Question

skills: classifying shapes, coordinate plane

1. classifying triangles: a triangle has one angle that is 110°. is it acute, right, or obtuse?
2. quadrilaterals: name a shape that has 4 right angles and 4

Explanation:

Step1: Recall triangle classification

Acute: all angles < \(90^\circ\); Right: one angle = \(90^\circ\); Obtuse: one angle > \(90^\circ\).

Step2: Compare given angle

Given angle is \(110^\circ\), which is > \(90^\circ\).

Answer:

Obtuse
