Best Answer

As long as all the angles of a Triangle add up to 180, it works. So 60 and 60 and 60 word

All triangles have 3 acute angles because 60+60+60= 180 which is correct for a normal triangle so yes

Mathematics is a discipline where exactitude is all-important.Whether all acute triangles are 'the same' depends on what you mean by same. Here are some possibilities for 'same', and whether all acute triangles qualify.The triangles are congruent (one fits exactly on top of another) ? No.The triangles are similar (same three angles) ? NoEach of the three angles is less than 900 ? YesSame no of sides ? YesA polygon ? Yes.A plane figure ? Yes.All acute triangles meet the last four criteria; some may meet the first two as well, but not all of them.

equilateral triangle, acute triangle, some isosceles and scalene triangles

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

Yes. Any triangle (in the standard Euclidian geometry) has at least 2 angles; some have 3.

Yes as in the case of an equilateral triangle that has 3 equal acute angles of 60 degrees that add up to 180 degrees.

no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.

Yes. Consider a triangle ABC with the following angles:A = 40B = 70C = 70Angles B and C are equal, which means the triangle is isosceles. All three angles are less than 90 degrees, which means the triangle is acute. Therefore, the triangle is both isosceles and acute.

It can have multiple right angles and also be purely of right angles

Yes.
