Answer 1

If you use three letters to name an angle, the middle letter MUST be the the name of the vertex.

Answer 2

B?

Answer 3

it's not A or B. I would go with C or D.

Answer 4

@mathstudent55 What do you think about C?

Answer 5

From quizlet.com:

3 ways to name an angle:

1 the vertex point if there are no other angles at the vertex that be confused.
2 three letters with the vertex as the center letter and the other letters representing points from each side.

3 a small number if one is given in the angle.

Answer 6

It looks like it's C. [:

Answer 7

Yay! :)

Answer 8

Do you know this? I think it's C or D....
Angle P is an acute angle.
Which could be the measure of angle P?
  A. 180°
  B. 125°  
C. 90°  
D. 65°

Answer 9

Answer 10

We know that an Acute angel is lesser than 90°
Which is lesser than 90 from the following choices?

Answer 11

An acute angle has a measure of between 0 and 90 degrees. "Between" means that 0 and 90 are not included.

Answer 12

D?

Answer 13

correct (:

Answer 14

correct

Answer 15

Yay!

Answer 16

Answer 18

Answer 19

I'll explain these terms, one at a time. Then you'll understand them.

Answer 20

Start with 2 lines:



I called the two lines m and n.

Answer 21

A transversal is a line that intersects two lines at two different points.

Answer 22

The figure now shows the lines, m and n, intersected by transversal t.
Another term for intersects is cuts. We can say that tranversal t cuts lines m and n.

Answer 23

When a tranversal cuts two lines, it forms 8 angles.

Answer 24

Now I'll number the angles in a similar way to your problem.

Answer 25

The angles can be grouped according to position.

Answer 26

Nvm, im too slow. lol Mathstudent can show you instead. he/she is a great teacher [:

Answer 27

Angles 1, 2, 7, and 8 are called "exterior" angles because they are on the "outside" of the two lines.
