Can some triangles have 3 acute angles?
All triangles have 3 acute angles because 60+60+60= 180 which is correct for a normal triangle so yes
Are all acute triangles the same?
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.
Triangle with all acute angles called?
equilateral triangle, acute triangle, some isosceles and scalene triangles
Do scalene triangles have acute angles?
Yes. Any triangle (in the standard Euclidian geometry) has at least 2 angles; some have 3.
Are some acute triangles equiangular?
Yes as in the case of an equilateral triangle that has 3 equal acute angles of 60 degrees that add up to 180 degrees.
Which shapes have only acute angles?
some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)

Some triangles have two obtuse angles and one acute angle?
Spherical triangles as on the earth's surface.
Triangle with all acute angles called?
equilateral triangle, acute triangle, some isosceles and scalene triangles

Does every triangle have to have an obtuse angle?
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.
Are some isosceles triangles acute?
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.
Are triangles equilateral?
Triangles can be classified into different shapes. Equilateral ; All sides the same length ; all angles equal 60 degrees. Isosceles ; Two sides the same length ; two angles equal size. Right-Angled ; Three sides can be of different lengths ; MUST have one right-angle. Scalene ; All sides of different lengths ; all angles of different size. Common 2-dimensioanal characteristics for ALL triangles. ; - They contain three(3) sides They contain three(angles) The internal angles ALWAYS sum to 180 degrees. A triangle may also be named a TRIGON ; A polygon of three sides. NB Triangles drawn on a 3-dimensional surface ( sphere ), the above characteristics can vary.
Are some scalene triangles acute?
Yes.
Are some acute triangles equidistant?
yes
