What triangle has one angle that measures 40 degrees one angle that measures 90 degrees and another angle that measures 50 degrees?
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
How do you classify a triangle with only one angle?
If you only know one angle, that angle is greater than 90 degrees, then the triangle is obtuse If that angles is equal to 90 degrees, then the triangle is a right triangle. If it is less than 90 degrees, you don't know enough information to classify the triangle.
Does a right triangle have an obtuse angle?
No, a right triangle must have a right angle (by definition). Because there is 180 degrees in a triangle and a right angle is 90 degrees, that leaves the remaining two angles having to equal 90 degrees. Therefore, a triangle cannot have an obtuse angle.
What is acute angle and isoseles angle?
acute angle is an angle that is less that 90 degrees. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
What triangle has no equal sides and one angle more than 90 degrees?
An obtuse triangle.
What are the classifications of a triangle?
The classifications of a triangle are:Right Triangle- has one angle that is 90 degreesEquilateral Triangle- has three equal sides and three equal angles (each is 60 degrees)Isosceles Triangle- has two equal sides and two equal anglesScalene Triangle- has no congruent sidesAcute Triangle- has three acute angles (less than 90 degrees)Obtuse Triangle- has one obtuse angle (more than 90 degrees)
Why is it impossible for a equilateral triangle to have a right angle?
An equilateral triangle has all three sides of equal length and all three angles measuring 60 degrees. A right angle, by definition, measures 90 degrees, which exceeds the angle measurements of an equilateral triangle. Since the sum of the angles in any triangle must equal 180 degrees, having one angle as 90 degrees would require the other two angles to sum to 90 degrees, violating the property of equal angles in an equilateral triangle. Therefore, it is impossible for an equilateral triangle to have a right angle.
What type of triangle has an angle that measures 20 degrees and and angle that measures 90 degrees?
Any triangle that has an angle measuring 90 degrees is a right triangle.
Can a triangle be classified as an acute triangle?
Yes. A triangle can be classified as: For angles 1. If a triangle has at least 1 angle that has an angle measure of more than 90 degrees, it can be called an obtuse triangle 2. If a triangle has 3 angles that are less than 90 degrees, it's a acute triangle. 3. If a triangle has an angle that has an angle measure of 90 degrees, it can be called and right triangle For sides: 1. All equal sides= equilateral. 2. 2 equal sides= Isosceles 3. No equal sides= scalene
Can a right angled triangle have all equal sides?
No, a right-angled triangle cannot have all equal sides. A triangle with all equal sides is an equilateral triangle, and in such triangles, all angles are equal to 60 degrees, which does not satisfy the condition for a right angle (90 degrees). For a triangle to be right-angled, it must have one angle that is exactly 90 degrees.
