Angles and more in ART

Point

An exact place in space with no definite shape and size

This picture shows points because the whole image is only made of points, and no lines.

Line Segment

Part of a line that can be measured.

This image is an example of line segments because it includes lines in the face that can be measured, aka line segments.

Plane

A flat surface that goes through three points and extends endlessly.

This picture shows planes intersecting at different lines.

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.

Straight Angle

An angle that measures exactly 180°

This image is an example of a straight angle because the picture is only made of lines.

Vertical Angles

Angles that intersect, and the opposite angles created are congruent.

This picture shows verticle angles because of the lines separating the patterns are vertical angles.

Complimentary Angles

This image is an example of complimentary angles because of the two angles in the right angle on her right cheek make 90°.

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.

Skew Lines

Two lines that do not intersect but are not parallel

This picture represents skew lines because of the line at the bottom going side to side, and the line at the top right that is coming towards you will never intersect, but are not parallel, so they are skew lines.
