Best Answer

It's acute.

Sum the squares of the shorter two sides and compare to the square of the longest side.

If the sum is less, the triangle is obtuse.

If they are equal, the triangle is right angle.

If the sum is more, the triangle is acute.

132 + 152 = 169 + 225 = 394

172 = 289

Sum is more so triangle is acute.

it is an acute triangle.

First you would square the length of each of the sides. You'd add the squares of the smaller two numbers. If they are smaller than the square of the biggest side, then the triangle is obtuse. If their sum is bigger, then the triangle is acute. If they are equal, then the triangle is a right triangle.Example:length of sides-23, 34, 49232+342__492529+1156__24011685

First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.

The answer depends on what point of concurrency you are referring to. There are four segments you could be talking about in triangles. They intersect in different places in different triangles. Medians--segments from a vertex to the midpoint of the opposite side. In acute, right and obtuse triangles, the point of concurrency of the medians (centroid) is inside the triangle. Altitudes--perpendicular segments from a vertex to a line containing the opposite side. In an acute triangle, the point of concurrency of the altitudes (orthocenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Perpendicular bisectors of sides--segments perpendicular to each side of the triangle that bisect each side. In an acute triangle, the point of concurrency of the perpendicular bisectors (circumcenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Angle bisectors--segments from a vertex to the opposite side that bisect the angles at the vertices. In acute, right and obtuse triangles, the point of concurrency of the angle bisectors (incenter) is inside the triangle.

An obtuse triangle does not always have three congruent sides. An obtuse triangle can be any form that always has three angles.

right triangle , a obtuse triangle, and a acute triangle

The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.

If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.

An acute angled triangle, right angled triangle or obtuse angled triangle.

An obtuse triangle is a type of triangle that has no congruent sides. Basically none of its sides are the same size.

Right triangle= has a right angle Acute triangle= has an acute angle Obtuse triangle= has an obtuse angle Equilateral triangle= all sides are the same length Scalene triangle= has no sides the same length Isosceles triangle= has only two sides the same length the triangles here make perfict dildose and condoms

Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.

A scalene triangle can have an obtuse angle and two different acute angles.
