congruent alternate interior angles

This is a picture of congruent alternate interior angles. The are in the interior of the line, so are interior. They are also congruent to each other since they are seperated by a line. The purple marks represent the angles. This picture is obviously a window, a window is used so you can see out of it. I toook this picture with my phone in front of Severn School.

congruent acute angles

This is a picture of congruent acute angles, they are all the same shape and measure so they are congruent to each other. This is a picture of chopsticks, so they can be found in the food industry. You can get them-not these in particular- at Panda Express or your favorite chinese food restaurant. Yum...

a line perpendicular to a plane

This is a picture I took with my own phone. It represents a line that is perpendicular to a plane. The line intersects the plane, making a right angle to the plane, which means it is perpendicular to the plane. This is a picture of a light "post" coming out of the ceiling used to hold a light fixture, maybe? It can be found in Dr. Chang's room.

skew lines

This is my own picture of my bedroom cabinets. These lines represent skew lines, which are lines that do not intersect and are not coplanar. The purple line represents the edge of my cabinet. The green line is on another plane, my window. The green line does not intersect with the purple line. I took this picture with my phone.

Segment bisector

This is my own image of a segment bisector, it is an image of my window shade. A window shade is used so you can control how much sun comes in and out. The blue line, the shade, is a segment. The red line is the bisector that divides in the segment in half. The purple lines represent congruent measures of the segment. This is my own photo from my phone.

Parallel lines

This is a picture of three parallel lines that are coplanar. These lines are from my bedding on my bed, so they are used for sleeping in comfort. The whole bed sheet serves as a plane, while the lines are in the plane. This is my own picture.

vertical angles

This i san image of blender blades, which have to do with the food industry. The blades are usually used for chopping up foods, they are not used as weapons in the upcoming Mission Impossible, so don't get confused. The purple lines represent vertical angles, meaning if they are the are on opposite sides and make an "X" looking thing. They are also congruent to each other.
