What kind of triangle do you have if it has an obtuse angle?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
Is a scalene triangle obtuse?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
What triangle has no congruent sides?
Scalene triangle
Scalene triangle: no congruent sides and no congruent angles (no sides of equal length and no angles of equal measure).
Can an isosceles triangle be obtuse?
Isosceles triangles always have two equivalent interior angles, and all three interior angles of any triangle always have a sum of degrees. Since this is an obtuse isosceles triangle, the two missing angles must be acute angles.
Why can’t a triangle have two obtuse angles?
No, because the sum of three angles of a triangle is 180 degree & sum of any two obtuse angles is always more than 180 degree. So, it can not be possible that a triangle have two obtuse angles.
Is a scalene triangle always acute?
In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).
What type of triangle has 3 unequal sides?
scalene triangle
Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
What do you call a triangle with all sides are congruent?
An equilateral triangle means that the three sides of your triangle are all congruent.
Can an obtuse triangle be isosceles Why?
A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angle? it is more than 90 degrees. An obtuse triangle may be isosceles or scalene.
Is it possible to have an obtuse isosceles triangle and why?
It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An oblique triangle is any triangle that is not a right triangle. It may be acute, obtuse, equiangular, scalene, isosceles, or equilateral, but not a right triangle.
