a right triangle has one right angle and two acute angles
Since the angles of a triangle add up to 180°, if one of the angles is a right angle (definition of a right triangle) then the sum of the other two will be 90°. If we designate the measure of the smaller acute angle as "x" then the other angle will be "4x" and: x + 4x = 90° so 5x= 90° and x = 18°
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
Acute angles
An equilateral triangle.
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
An acute triangle.
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
a right triangle has one right angle and two acute angles
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle

No A right angle has 90 degree A triangle has 180 degreeYes, a right triangle has one right angle and two acute angles. The sum of the acute angles is 90°.
A triangle with a right angle is a right triangle.
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
