For starters, here are the basic rules of triangles.
- A right angle is 90 degrees.
- An acute angle is less than 90 degrees.
- An obtuse angle is more than 90 degrees.
- A triangle's angles always add up to 180 degrees.
- An isosceles triangle has two sides that are the exact same length and thus two same angles.
Now, an isosceles triangle can have all acute angles. For example, its angles can measure in degrees at 80, 50, and 50. However, isosceles triangles can also have an obtuseangle.
For example, consider a triangle with the following angle degree measures: 96, 42, 42.
With the rules above in mind, the triangle above is an isosceles triangle because two angles are the same and they both are acute. At the same time, the remaining angle is greater than 90 degrees and so is obtuse. Thus, a single triangle can have both acute and obtuse angles.
Similarly, you can have a right triangle that is also isosceles, with the angle degree measurements at 90, 45, and 45.

What is acute angle and isoseles angle?
acute angle is an angle that is less that 90 degrees. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
Which triangle has 1 acute angle and 1 obtuse angle?
It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles
Is is possible for an isosceles triangle to be an acute triangle?
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
A triangle containing 1 right angle and 2 congruent acute angles is called?
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
