Which set of angles Cannot form a triangle?
The angles of the triangle always sum to 180 degrees.
Therefore the angles has to be less than 180 degrees.
So, any set of three angles that add up to 180 degrees can form a triangle..
What is an angle of a triangle?
The angle of a triangle is the space formed between two side lengths of a triangle. A triangle contains interior angles and exterior angles. Interior angles are three angles found inside a triangle. Exterior angles are formed when the sides of a triangle are extended to infinity.
Could 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.
Does a triangle have one right angle?
A triangle that has one right angle is called a right triangle. … The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent.
Can a triangle have 1 right angle?
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure). …
Can you have a triangle with 2 obtuse angles?
No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.
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 2 right angles?
No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. So, if a triangle has two right angles, the third angle will have to be 0 degrees which means the third side will overlap with the other side.
Does a triangle have 4 right angles?
The “3,4,5 Triangle” has a right angle in it. (Draw one if you ever need a right angle!) And, like all triangles, the three angles always add up to 180°.
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°.
Can a triangle have all its angles acute?
A triangle can never have only one acute angle. If a triangle has 1 acute angle, the other angles will be either right angles or obtuse angles which is not possible as the sum of interior angles of a triangle is always 180°. So, every triangle needs to have at least 2 acute angles.
Can a triangle have one obtuse and right angle?
Answer and Explanation: No, a triangle cannot have an obtuse and a right angle.
Why can a triangle only have one right angle?
A triangle can’t have 2 angles with measures of 90 degrees or more, since the measures of the interior angles of a triangle add to 180. Thus in any triangle, at most 1 angle has measure 90 or more, and the other two angles have to be acute.
How many right angles does a triangle have?
one right angle1 Answer. Daniel L. A right triangle has only one right angle.
What is the greatest number of right angles in a triangle?
Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .
