no. the total degrees of a triangle have to add up to 180 degrees. since all the angles have to be the same, all the sides have to be the same.
An equilateral triangle is when all angles and sides are equal throughout the triangle. If the triangle has same sides then it has same angles. Acute triangle is when all angles in the triangle are under 90 degrees. Since all triangles have three angles, and the sum of all angles within any traingle equals 180degrees, we must divide 180degrees by 3 angles.... 180deg/3A= 60deg per angle... This is the only option since there is only one equilateral triangle set of angles (60/60/60). And all the angles are under 90 deg. So in other words an equilateral triangle is an acute triangle.
An equilateral triangle can not have "other" shapes.
A right triangle. * * * * * Not necessarily. All that can be said is that is is not an equilateral triangle. It can be isosceles or scalene. It can be acute angled, right angled or obtuse angled.
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
Any irregular polygon can have an acute angle. A regular triangle (equilateral) has three acute angles. All other triangles must have at least two acute angles. A quadrilateral, other than a rectangle (or square), must have at least one.
It depends. If they're all 60 degrees then it's an equilateral triangle., but it could be some other combination, sayy 60, 59, 61, just for example.
All angles of an equilateral triangle are congruent, in other words, they all have the same angle measure. Since these three equal angles must add up to 180 degrees, each angle must have the measure of 60 degrees. This is because 60 X 3 = 180 degrees. So, the angles of an equilateral triangle are all equal to 60 degrees. An angle that is less than 90 degrees is an acute angle, and since 60 is less that 90, the angles of an equilateral triangle are acute.
No. Within a triangle, the sum of all of the angles must equal 180 degrees. All three angles are acute (60 degrees) in an equilateral triangle, while only two are in a right triangle, the other being a right angle (90 degrees). There obviously could not be three right angles (270 degrees).
Yes. In this case a triangle is called an acute triangle.
how you name a triangle by its angles is like acute, obtuse, or right triangle. you do that by seeing if the angle has a 90 degree angle in it then its a right angle, if all the angles are 90 degrees or less than its an acute triangle. and if the triangle has one angle that is over 90 degrees than it is an obtuse triangle. to name a triangle by its sides is if its equilateral, equiangular, or regular. if its equilateral then all the sides are congruent. if its equiangular then all the angles are congruent. if its regular, then all the sides and angles are congruent to each other (for example and octogon). :)
An equilateral and right triangle are contradictory.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classed as follows- 1 Scalene triangle has 3 different acute angles 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has 1 obtuse angle and 2 different acute angles 4 Isosceles triangle has 2 equal acute angles and 1 other angle 5 Equilateral triangle has 3 equal 60 degree angles
