Parallel Lines•The green lines show that the buildings are parallel.•Buildings are parallel because it provides an even and steady platform.•Parallel Lines are lines that do not intersect.

Right Angles•The blue building on the right has a right angle.•The right angle add some sort of extra support to the building.•Right angles are angles that are 90 degrees

Linear Lines•The white line shaped as a cross on the window frame is linear.•It provides support for the windows.•Linear lines are supplementary, they form 180 degree angles.

Vertical Angles•The black lines show that they are vertical angles.•It provides support for the bridge.•Vertical angles are angles that are made congruent by 2 intersecting lines.

Skew Lines•The bridge and the road are skew.•The bridge on top of the road is a freeway and makes travel faster•Skew lines are lines that do not intersect and are not parallel.

Intersecting lines•The train tracks are intersecting.•This allows the trains to make turns and go different directions•Intersecting lines are lines that cross each other.

Angle Bisector•The knife is the bisector and the wood is the angle.• The knife is cutting the wood in half equally.•Angle bisector is the division of 2 equal parts, usually by a line.

Line segment•The screw is a line segment, it has 2 end points.•Line segment is a line with 2 end points.

Midpoint•The pole on the bottom of the sign marks the midpoint of the sign.•The pole provides support for the sign.•A midpoint is a middle point of a line segment. It is equidistant from both endpoints

Acute angles•The window being opened makes an acute angle. And angle less than 90 degrees.•This allows the window to be opened.

Supplementary angles•The blue boxes indicate that there are 2 90 degree angles. This means that they are supplementary. They add up to 180 degrees.•The wood helps support the window frame.

Alternate exterior angles•The blue lines show that they are alternate exterior angles. It is cut by a transversal and they are equal.

Alternate interior angles•The blue lines show that they are alternate interior angles. They are cut by a transversal and opposite of each other

Coplanar points•Points A and B are coplanar because they lie on the same plane.•Coplanar points are points that lie on the same plane.

Congruent•The 2 buildings with marks are congruent. •They are congruent because they have the same shape and size.
