Question

A triangle with angle measures of 20° and 30° _______________________ is triangle.

Answer 1

There is no diagram

Answer 2

are you supposed to figure out the type of triangle or?

Answer 3

The choices are an acute, an obtuse, or a right triangle.

Answer 4

okay gimmie a second

Answer 5

Okay

Answer 6

Can you tell me what the 3rd angle of the triangle would be
Calculate it. The sum of the angles of a triangle add up to 180.

Answer 7

I also have 3 more after this one

Answer 8

130?

Answer 9

Good based on that, can you tell me what kind of triangle it is?

Obtuse triangles have an angle that is greater than 90
Acute have all there angles less than 90

Answer 10

Because 20° + 30° = 50° and subtract 180° and 50° to get 130°

Answer 11

The answer is obtuse?

Answer 12

That's correct

Answer 13

I have some more

Answer 14

On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 3 inches and one with a side length of 4 inches.

Which statement is true about the two triangles?


The two triangles are the same size but not the same shape.

The two triangles are the same size and same shape.

The two triangles are the same shape but not the same size.

It is impossible to construct equilateral triangles with these side lengths.

Answer 15

The problem with this is that I don't have a protractor

Answer 16

You don't need one. Equilateral triangle means all three sides are the same

Answer 17

Okay

Answer 18

So 180 div 3?

Answer 19

\[180 \div 3?\]

Answer 20

Yes all angles will be equal too. Which answer do you think is correct

Answer 21

60 because 6 * 3 = 18. If you just add a zero like this, 60 * 30 = 180 you get the same answer just with zero's.

Answer 22

So it is, B. The two triangles are the same size and same shape?

Answer 23

Right?

Answer 24

Should I go with that?

Answer 25

Are they the same size? Remember one triangle has a side of 3 while the other is 4

Answer 26

C

Answer 27

C is correct

Answer 28

On a piece of paper, use a protractor to construct right triangle DEF with DE=4 in. , m∠D=90° , and m∠E=45° .

What statement is true about the triangle?


EF=7 in.

EF=4 in.

DF=2 in.

DF=4 in.

Answer 29

Do you know TGP?

Answer 30

Draw a triangle. DF is the hypotenuse. DE and EF are the legs of the triangle.
