 # Question: Can A Triangle Have 2 90 Degree Angles?

## Does a square have two 90 degree angles?

The diagonals of a square bisect each other and meet at 90°.

The diagonals of a square bisect its angles.

Opposite sides of a square are both parallel and equal in length.

All four angles of a square are equal (each being 360°/4 = 90°, a right angle)..

## Does 4 5 6 make right triangles?

Explanation: For a set of three numbers to be pythagorean, the square of the largest number should be equal to sum of the squares of other two. Hence 4 , 5 and 6 are not pythagorean triple.

## What are the 3 sides of a right triangle?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

## Can a triangle have two 90 degree angles?

Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.

## What are the angles of a 90 degree triangle?

A right angle has a value of 90 degrees (90∘ ). 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).

## Can a triangle have 3 acute angles?

A triangle where all three internal angles are acute (less than 90 degrees). … In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: Less than 90° – all three angles are acute and so the triangle is acute.

## Can a triangle have 2 acute angles?

Answer and Explanation: Yes, all triangles have at least two acute angles. Acute angles are angles that measure less than 90 degrees, while obtuse angles measure greater…

## Is a 3 4 5 triangle always 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. There are an infinite number of them, and this is just the smallest. See pythagorean triples for more information.

## How do you find an angle of a triangle with 3 sides?

To solve an SSS triangle:use The Law of Cosines first to calculate one of the angles.then use The Law of Cosines again to find another angle.and finally use angles of a triangle add to 180° to find the last angle.

## Does 9 12 and 15 make a right triangle?

The sum of the squares of 9 and 12 does indeed equal the square of the hypotenuse, h=15; therefore, the triangle is indeed a right triangle. Therefore, final answer: Yes, the triangle with sides 9,12 and 15 is a right triangle.

## Can a triangle have all angles less than 60 degree?

No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°. Hence, it will not be a triangle.

## What is the 3rd side of a triangle?

hypotenuseThe third side–the side opposite the right angle–is called the hypotenuse of the right triangle. The two shorter sides are usually called “legs.” This formula is called the Pythagorean Theorem in honor of Pythagoras.

## How do you find the third side of a triangle given two sides?

According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle. Add the two angles together and subtract the sum from 180 degrees to find the third angle.

## How do you find the third side of a triangle given two sides and an angle?

use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.

## How many acute angles Can a triangle have?

three acute anglesAn acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
