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.
yes, since angle is 45 degrees and thus less than 90, making it acute
Well, honey, a parallelogram has a grand total of zero acute angles. It's all about those congruent opposite angles being the same size, which means they're either both obtuse or both acute. So, if you're looking for acute angles, you better go find yourself a different shape to play with.
The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.
'a' and 'b' must both be acute, complementary angles.
No because a cube has only 4 right angles on each of its six faces.
They both have right angles, they both have sides of the same length (yes, on a cube, edges of the same length).
Not necessarily. Both may be right angles.
They both will be right angles that add up to supplementary angles 180 degrees
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.
Probably E - since it has four right-angles.
They are both either bigger or smaller than a right angle
none - it's an isoscelese triangle it doesn't have right angles. It has two equal angles (both acute) and one other andgle (also acute)
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
Yes, unless they are both right angles.
In every pair of complementary angles, both of them are acute angles.
