2 What is a point? A point is an exact location in space.
A point is denoted by a dot. A point has no size. This picture is a real world example of a point. It is a end of a pencil representing a point. I chose this picture because I believed it was a good example of a point.

3 What is a line? A line has 0 endpoints Doesn’t have a midpoint
It is infinitely long and straight This is a interstate it’s a real world example of a line. I chose this picture because interstates go on and are infinitely straight, it’s a good example.

4 What is a plane? A plane has two lines that cross to move 90 degrees
It is a flat surface Extends infinitely in all directions This desk top is a example of a plane. I chose this picture because students use this everyday at school and it is a flat surface that’s good as a example of a plane.

5 What is a segment? A segment has a midpoint
It is a straight a line which links two points without extending beyond them.

6 What is a ray? Has 1 endpoint Named by its endpoint
Extends infinitely long in one direction It is a portion of a line which starts at a point and goes off in a particular direction infinitely. This picture is a picture of the sun giving off rays. It is a good example of a ray in the real life world.

7 What is collinear points?
A set of points that lie in a straight line They are on the same line These computers are in a straight line and the same line. I chose this picture because it’s a great example of collinear points in the real life.

8 What is an acute angle? It is an angle that is less than 90 degrees
It’s a little angle and less than a right angle This picture is a picture of a piece of pizza. I chose this because it’s a little angle which is an acute angle. It was a good example.

9 What is an obtuse angle? It is an angle that is greater than 90 degrees This picture is a example of a obtuse angle. The pitcher has his legs angled as an obtuse angle and that is why I chose this picture.

10 What is an right angle? A angle that is measured exactly to 90 degrees
This is a example of a right angle. I chose this picture because the way the computer is opened it is at a right angle example.

11 What are perpendicular lines?
Perpendicular lines are two or more lines that intersect at a 90-degree angle. They intersect each other This sign is an example of perpendicular lines, and that is why I chose this picture.

12 What are complementary angles?
They are two angles that measure up to 90-degrees This clocks hands are a example of a complementary angle because it equals up to 90 degrees.

13 What are supplementary angles?
Two angles whose sum are 180-degrees A road like this is a good example for a supplementary angle. Because it equals up to 180 degrees.

14 GEOMETRY IN THE REAL WORLD PT 2 (TRIANGLES)

15 Vertical Angles each of the pairs of opposite angles made by two intersecting lines The picture shows vertical angles because they intersect

16 Acute Triangle all angles are less than right angles—each one is less than 90 degrees. In the picture all angles are less than 90 degrees

17 Obtuse Triangle  one angle is greater than a right angle—it is more than 90 degrees The picture shows one side that is an obtuse and other is straight.

18 Equilateral Triangles
all three internal angles are also congruent to each other and are each 60°. This rubic cube shows triangles that all sides are equal

19 Isosceles Triangles has two sides of equal length
This picture is a piece of pizza which two sides are equal and the other is not.

20 Scalene Triangle has three unequal sides
This picture shows all three sides are unequal
