What type of angle does a triangle have?
A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.
What type of angles are in an Isosceles triangle?
There are two equal acute angles. The third angle can be acute, right or obtuse.
If two angles of a triangle are acute must the the third angle always be acute?
No. In fact, if one of the angles is not acute (a right angle or obtuse), the other two must be acute.
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
Can an acute isosceles triangle have two angles that measure 40?
Yes and the third angle would be 100 degrees
