Question

Which of the following best describes triangle GFH?




A.

isosceles triangle


B.

acute triangle


C.

scalene triangle


D.

right triangle

Answer 1

review triangles
2 equal sides/angles = isosceles
90 degrees = right angle
3 different lengths = scalene
3 equal sides/angles = equilateral
less than 90 = acute
more than 90 = obtuse

Answer 2

the sum of the angles in a triangle = 180 degrees

Answer 3

one approach
write the expression for the sum of the angles set = 180
solve for x
find the value of the angles

Answer 4

any questions?

Answer 5

did you get x = 6?

Answer 6

yes thank you very much

Answer 7

scalene yes you are welcome

Answer 8

can I ask you a few more?

Answer 9

Identify the two remote interior angles that correspond to <5 @triciaal

Answer 10

sum of angles on a straight line = 180
<2 + <3 = <5

Answer 11

do you need more details?

Answer 12

yes please
