True are false A triangle with sides lengths 40 75 and 84 are a right triangle?
False.
A triangle has sides of lengths 6 2 and 7 is it a right triangle?
No. For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse): 22 + 62 = 40 72 = 49
Can a triangle have side lengths of 2 and 6?
Yes. One example would be an yes. One example would be an isosceles triangle with sides equal to 2,6 and 6. Another would be a right triangle with sides 1,6 and sq-root of 40 (approx 6.34)
Can a triangle be made with side lengths of 20 20 and 40?
Oh, dude, let me break it down for you. So, for a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 20 + 20 is 40, which is equal to the third side length. So, no triangle here, just a straight line. Like, nice try, but not today.
How many possible right triangles have an area of 20 units squared?
An infinite number. All you need is any right triangle where the product of the lengths of the two legs is 40.
