There are no numbers on that list that could be the sides of a right triangle. Oh, all right. The following is the answer:
Not necessarily. A triangle with two equal sides is called an isoceles triangle. A right triangle has one angle that measures 90 degrees.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
That is called a "Right Triangle"
It would depend how long it is.
A right triangle is a triangle in which one of the three angles measures 90°. In other words, it is a triangle with two sides that are perpendicular to each other.
right angled triangle
No. An isosceles right triangle has the measures of 90, 45, and 45. Isosceles means that two sides are congruent. Hope this helps :)
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
It can be because it depends on the triangle's angles. For example, if the triangle has 2 equal sides and a right angle it could be a isosceles and a right triangle.
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).
The hypotenuse is always the longest of the three sides of a right triangle.
