Yes.
'a' and 'b' must both be acute, complementary angles.
Two. Two acute angles in a right triangle.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
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.
They are complementary.
complementary
Perhaps because you've misspelled them. When written correctly,the acute angles of a right triangle AREcomplementary.
No, they are complementary angles. Supplementary angles sum to 180o Complementary angles sum to 90o. The three angles of a triangle sum to 180o. If one is 90o (the right angle), then the other two sum to 180o - 90o = 90o and so are complementary.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
They sum to 90 degrees so they are complementary.
'a' and 'b' must both be acute, complementary angles.
A right angled triangle can only have two acute angles.
Two. Two acute angles in a right triangle.
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.
