## Is a scalene triangle always acute?

An Acute scalene triangle is a triangle in which all three angles are different measuring and each of less than 90°. An acute scalene triangle is showing its unequal sides. All three angles are different in measure implies that all three sides of an acute scalene triangle are also different in length.

Any triangle in which the Euler line is parallel to one side is an acute triangle. Acute triangles can be isosceles, equilateral, or scalene. The longest side of an acute triangle is opposite the largest angle. In an acute triangle, the following is true for the length of the sides:

Yes, every equilateral triangle is an acute triangle. We have the following property about the measures of the angles of any equilateral triangle. A… See full answer below.

No. There can be an obtuse angle or a right-angle in an isosceles triangle.

By definition, an acute isosceles triangle will have at least two sides (and at least two corresponding angles) that are congruent, and no angle will be greater than .

An equilateral triangle has three acute angles. Every triangle is made up of three sides.

Hi Chris. You are right – an equilateral triangle cannot have an obtuse angle. An equilateral triangle has all three sides the same, therefore all three angles are the same. When you add up the angles of any triangle, you get 180 degrees, so 180 divided by 3 is 60 – the size of every angle of any equilateral triangle.

Note: The angles in an equilateral triangle are also of equal measures (60º each). An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. A right triangle has one right angle.

A scalene triangle can be acute-angled or obtuse-angled or right-angled.

Every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.

An acute triangle is a triangle in which each angle is an acute angle. Any triangle which is not acute is either a right triangle or an obtuse triangle. For example, an equilateral triangle is always acute, since all angles (which are 60) are all less than 90.

In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).
