The 2 horizontal lines are parrellel beacuase they don't intersect and they are on the same plane. The vertical line is a perpendicular transversal because it intersects both of the parrellel lines. The vertical line is perpendicular to the horizontal line because vertical lines are always perpendicular to horizontal lines.
Parallel Lines with Perpendicular Transversal
Parrellel Lines With No Transversal A-2
The two lines marked are parrellel because they don't intersect. There aren't any lines that intersect the parrellel lines so therefore there is no transversal.
Parrellel Lines With A Non-Prependicular Transversal A-3
The horizontal lines at the top of the bricks are parrellel to one another because they don't intersect. The hand rail is a transversal because it intersects the two parrellel lines.
Vertical Angles Formed By Intersecting Lines B-1
Vertical angles are a pair of oppisite angles that are congruent and made by intersecting lines. The criss-cross gate bars make congruent pairs of vertical angles.
Central Angle In A Circle G-1
A central angle is an angle whose vertex is the center of the circle. The hands of the clock make up the angle. The center of the clock (the circle) is where the hands meet. The angle's vertex is where the hands meet which is the center.
Circle With >7 Diameters H-3
The diameters of the bike tire are the spokes of the tire. They are the diameters because they cut through the white and red center.
Quad That's Equiangular But Not Equilateral K-2
A Quad is a four, straight sided closed shape, just like this piece of ply wood. The ply wood is equiangluar because it has 4 congruent right angles, but it's side lengths are not congruent (equal in length.)
Congruence Transformation O-1
The two push bottons are an example of a congruence transformation. The one on the left is the pre-image and on the right is the image. There is only a translation between these two bottons which means both angle measures and side lengths were preserved. When angle measures and side lengths stay the same then it's a congruence transformation.
Similarity Transformation O-2
A similarity transformation preserves angle measures and general shape. This photo of two different sized shells shows an enlargenment. The general shape, deatils and angle measures are the same but the sizes are different.
