Yes. In fact, it must contain TWO angles of measure less than 90 degrees.
No, an equilateral triangle does not have right angles. All three interior angles of an equilateral triangle are equal and measure 60 degrees each. Since right angles measure 90 degrees, an equilateral triangle cannot contain any right angles.
No right triangle can have any obtuse angles inside it.
angles that measure 90 degrees.
A Triangle which do not have a right angle.
An acute triangle.

Two. Two acute angles in a right triangle.
angles that measure 90 degrees.
Equilateral Triangles do not contain right angles, since all angles in this shape are equal and it is impossible to make a triangle that consists of three 90 degress angles. Isosceles and Scalene may contain a right angle.
90 degrees
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Is a right angled triangle.
A Triangle which do not have a right angle.
An acute triangle.
No.
Yes in a 90 45 45 triangle
