Yes you can.
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
The perimeter of any triangle is the sum of its 3 sides
A triangle with side a: 36, side b: 20, and side c: 20 meters has an area of 156.92 square meters.
No. Pythagoras' theorem states that when the square of the hypotenuse is equal to the sum of the squares of the other two sides then it is a right-angled triangle. The hypotenuse is the longest side (opposite the supposed right angle). In this case the hypotenuse is 20. The square of 20 is 400. The other two sides are 12 and 15. The square of 12 is 144 and the square of 15 is 225. The sum is therefore 225 + 144 = 369, which is not equal to 400, therefore the triangle cannot be a right-angled triangle.
Yes. Using Pythagorean's theorem: 202+212 = 400+441 = 841 = 292 = 841
The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
No
It is not possible because 9+8 is not greater than 20.
It is not possible to have a triangle with sides of those lengths. The two shortest sides of a triangle must always add to more than the longest side. This is known as the triangle inequality.
True
The area of triangle is : 100.0

TRUE
(3*202)+(1/2*20*17.32) = 1373.2 square feet

False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.
Yes, because the equation for solving a right triangle's hypotenuse is a2 + b2 = c2. So lets say 16 is a and 12 is b and 20 is c. Now a=256 and b=144 and c=400. Because 256 + 144 = 400 these measurments would make a right triangle. Understand?
