All angles in a scalene triangle are acute?
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
Does an acute triangle only have one acute angle?
No it has three acute angles
What are three types angles?
Right Angle, Acute Angle, and Obtuse Angle
Does an isosceles triangle have to have three acute angles?
No. The angle that isn't acute must be the unique angle, though.
Can a quadrilateral have three acute angles and one right angle?
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.

No it has three acute angles

What are the three angles?
Acute angle, right angle and obtuse angle
If angle 3 is actue what is the other angles?
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
Does an isosceles triangle have to have three acute angles?
No. The angle that isn't acute must be the unique angle, though.
What angle does the letter M have?
It has three acute and three reflex angles.
Why do all triangles have acute angles?
A triangle is a three-sided figure with three angles, two or three of which (depending on the triangle) must be acute angles. The sum of all of the angles has to equal 180° - no more, no less. An acute angle is an angle of less than 90°. If one of the angles of a triangle is 90° or more (it is a right angle or obtuse angle) the SUM of the other two angles cannot exceed 180° minus the degree of the first angle. Therefore the two remaining angles must be less than the first angle, which means that they have to be acute angles.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
Can a quadrilateral have three acute angles and one right angle?
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
What shape has an acute angle and three right angles?
No plane geometric figure can have one acute and three right angle only, at least two other angles must be included
Is an equilateral triangle have a acute angle in it?
An equilateral triangle has three acute (60 degree) angles.
