# Angles and more in ART

### By: Mercedes Preston Period: 4

## Acute Angle

*An angle that measure less than 90°*

*The image on the left represents acute angles because of the acute angles in the bees wings.*

## Obtuse Angle

*An angle that measures more than 90°*

*The middle picture represents an obtuse angle because of the right side of the pink triangles, and the red and blue squares being the bottom part of the angle.*

## Right Angle

*An angle that measures exactly 90°*

*The right picture represents a right angle because of the right angles in Rihannas hair.*

## Supplementary Angles

*A pair of adjacent angles, and when they are added together, they measure 180°*

*The picture on the left represents supplementary angles because of the two angles created by the officer pulling back the wood.*

## Parallel Lines

*Two lines that run beside each other, and never intersect.*

*The middle picture represents parallel lines because all of the lines in the image are parallel.*

## Perpendicular Lines

*Two lines that intersect, and the angles that are created all measure 90°*

*The image on the right is an example of perpendicular lines because the two bold lines in the squares create perpendicular angles.*
