A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
What is the definition of a right triangle in geometry?
A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base. Here’s what a right triangle looks like: Types of right triangles.
How do you explain a right triangle?
Right Triangle. A right triangle is a triangle with one right angle (one angle equal to 90°). The side opposite the right angle (the longest side) is called the hypotenuse. The remaining two sides (the sides that intersect to determine the right angle) are called the legs of the right triangle.
What is an example of a right triangle?
Example: The 3,4,5 Triangle The “3,4,5 Triangle” has a right angle in it.
Which 2 terms describe right triangles?
A right triangle is a triangle with one right angle. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. The angles opposite the legs, by definition, are complementary.
What are the 3 sides of a right triangle?
Hypotenuse, opposite, and adjacent (article) | Khan Academy.
Is 345 a right triangle?
Any triangle whose sides are in the ratio 3:4:5 is a right triangle. Such triangles that have their sides in the ratio of whole numbers are called Pythagorean Triples.
Does 4/5 and 6 make a right triangle?
The three numbers 4, 5, 6 make a Pythagorean Triple (they could be the sides of a right triangle).
