Which set of side lengths form a right triangle?

14 m, 20 m, 25 m
3 ft, 6 ft, 5 ft
10 cm, 6 cm, 8 cm
7 cm, 8 cm, 10 cm
Help quick please!

C

Step-by-step explanation:

You know the triangle is right if the squares of the two smaller side lengths add up to the square of the largest side length, thanks to the Pythagorean Theorem: , where a and b are the legs and c is the hypotenuse.

Let's put this to the test for each answer choice:

A) --> 196 + 400 =? 625 --> 596 is NOT equal to 625, so wrong

B) --> 9 + 25 =? 36 --> 34 is NOT equal to 36, so wrong

C) --> 36 + 64 =? 100 --> 100 DOES equal 100, so correct

D) --> 49 + 64 =? 100 --> 113 is NOT equal to 100, so wrong

Thus, the answer is C.

Hope this helps!

10 cm, 6 cm, 8 cm

Step-by-step explanation:

Longest side is the hypotenuse

10² = 6² + 8²

100 = 36 + 64

100 = 100

Satisfies pythagoras theorem, hence forms a right angle triangle

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
