how many formulas do you know for finding the area of triangles

5

100

What is the perimeter of a triangle with side lengths of 4, 7, and 9?

What is P=20

200
the difference between isosceles and scalene
What is isosceles triangles have 2 equivalent sides and angles, scalene triangles have no equivalent sides and angles
200
if b=3 and h=4, A=?
What is A=6
200

What is the perimeter of a triangle with side lengths of 2.4, 3.17, and 8.75?

P=14.32

Line up the dot and fill in any empty place values with 0.

P=2.40+3.17+8.75

300
the sum of all angles in a triangle
What is 180 degrees
300

given right triangle, legs are 5 and 6cm, find the area

15

300

What is the perimeter of a scalene triangle with a height of 17, a base of 23, a side length of 17, and another side length of 13?

What is P=63

We don't use the height to help find perimeter because it does not go around the edge of the triangle.

400
The measure of all angles in an equilateral triangle
What is 60 degrees
400

given triangle, all sides are 8cm. find its area

16 root3

400

If the perimeter of an equilateral triangle is 36, what is the side length of the triangle?

12.


36 divided by 3 = 12

500

if the angles measure: 90, 35 and 55 degrees, how would you classify the triangle 

What is a right triangle

If the perimeter of a rectangle is 29 and has a side length of 8 and another side length of 11, what is the length of the last side?

What is 10.

11+8=19; 29-19=10.
