Is a triangle with sides of lengths 20 21 and 29 a right triangl?
Yes because the given dimensions comply with Pythagoras's theorem for a right angle triangle.
A triangle with sides of lengths 12 15 and 20 is a right triangle?
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.
What is area of a triangle whose base measures 3 meters and sides are 20 meters each Height unknown?
A triangle with side a: 3, side b: 20, and side c: 20 meters has an area of 29.92 square meters.
Can the same perimeters have a different area?
yes. for example imagine a cube with a length of five on all sides. its perimeter would be 20 and its area 25. now make it a rectangle with 6 as two lengths and 4 as two lengths. its perimeter is 20 but its area is 24
Does 10 yards 15 yards and 20 yards make a right triangle?
No
Triangle with sides of lengths 20 21 and 29 is a right triangle true or false?
TRUE
A right triangle has sides of lengths 15 and 20 and 25 units. What is the perimeter of the and 8203 triangle?
The perimeter of any triangle is the sum of its 3 sides
Is a triangle with sides of lengths 20 21 and 29 a right triangl?
Yes because the given dimensions comply with Pythagoras's theorem for a right angle triangle.

The lengths of the legs of a right triangle are 15 centimeters and 20 centimeters What is the length of the hypotenuse?
The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
Is a triangle with sides of lengths 20 21 and 29 a right triangle?
Yes. Using Pythagorean's theorem: 202+212 = 400+441 = 841 = 292 = 841
Is A triangle with sides of lengths 12 15 and 20 a right triangle?
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.
How do you know if a triangle is a right triangle using the pythagorean therom?
We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
Is a triangle with sides of lengths 20 21 and 30 a right triangle?
No.(20)2 = 400(21)2 = 441(20)2 + (21)2 = 881(30)2 = 900(20)2 + (21)2 is not equal to (30)2
If a right triangle has sides of 16Cm and 12Cm what is the hypotenuse?
If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm
The side of a triangle 78cm 20 cm and 22cm find its area?
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.
Can three sides of 25m 15m and 5m form a triangle?
Triangle inequality says that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.Since 15 + 5 = 20 < 25, we cannot draw a triangle.
