It is true because a triangle with a right angle and two acute angles is a right angle triangle.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
They both have at least two acute angles. Their centroid is not outside the triangle.
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
No. An acute triangle has to have three acute angles. A right triangle has to have one 90 degree angle.
Sometimes an isosceles triangle but never a scalene triangle with 3 interior acute angles.
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse 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.
No.
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
