Acute triangle has all angles less than 90 degrees.Right-triangle has one 90 degrees angle.Obtuse triangle has one angle more than 90 degrees.Additional Information:-Isosceles triangle has 2 equal angles plus another angle and they add up to 180 degreesEquilateral triangle has 3 equal interior 60 degree angles

If it is an equilateral triangle then it will have 3 equal angles If it is an isosceles triangle then it will have 2 equal angles plus another different size angle

Yes in a right angle triangle it does because it is Pythagoras' theorem.

In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared

That a right angle triangle's base when squared plus its height when squared is equal to its hypotenuse when squared:- a2+b2 = c2

No. An interior angle plus its exterior partner add up to 180 degrees. In order for an exterior angle to be acute, its interior partner would have to be obtuse, which doesn't happen in an acute triangle.

Yes: 1 interior angle plus 1 exterior angle = 180 degrees

An isosceles triangle will have equal sides and 2 equal angles of 45 degrees plus a 90 degree angle.

If it is an equilateral triangle then it will have 3 equal angles If it is an isosceles triangle then it will have 2 equal angles plus another different size angle

Because the 3 interior angles of a triangle add up to 180 degrees no more and no less but a right angle plus an obtuse angle would be over 180 degrees.

All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- 1 Scalene triangle has 3 acute angles of different sizes 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has an obtuse angle and 2 acute angles 4 Isosceles triangle has 2 equal angles plus another angle 5 Equilateral triangle has 3 equal 60 degee angles

Yes in a right angle triangle it does because it is Pythagoras' theorem.

In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared

That a right angle triangle's base when squared plus its height when squared is equal to its hypotenuse when squared:- a2+b2 = c2

In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
