Google Classroom

Problem

Drag the vertex of the angle to place the vertex at point A.
Drag another point on the angle to make one of the rays go through point B.
Make the other ray go through one of the unlabeled black points to create an acute angle.
The arc symbol near the vertex indicates the angle being measured.
This is an acute angle because its measure is
90∘.
