Can a scalene have a 60 degree angle?

Can a scalene have a 60 degree angle?

60 degrees – 60 degrees – 60 degrees is not a scalene triangle since the angle measures are not all different. 120 degrees – 10 degrees – 50 degrees is a scalene triangle since all the angle measures are different.

What are the rules of a scalene triangle?

All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.

What is the angle of a scalene triangle?

A scalene triangle is a type of triangle with all its three sides having different lengths with the sum of three of its angles being equal to 180 degrees.

Is a scalene triangle a right triangle?

A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

What is Stalin triangle?

Can a scalene triangle have equal angles?

Scalene triangle It also has no equal inside angles. These triangles can be acute (all angles less than 90°), right-angled (one angle is 90°), or obtuse (one angle is more than 90°).

How do you find the angle of a scalene triangle with two sides?

“SAS” is when we know two sides and the angle between them. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.

What makes a scalene triangle a scalene triangle?

A scalene triangle is a triangle in which all three sides have different lengths. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent. Example 1: In the triangle shown, all the three sides have different lengths.

How do you find the angle of a triangle with one angle?

Use the sine rule if given only one angle and two lengths of a triangle. The formula is sin A/a = sin B/b, where “A” and “B” are angles and “a” and “b” are the lengths of the sides opposite these angles, respectively.

What are the characteristics of scalene triangles?

Definition A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees. Thus, it meets the angle sum property condition of triangle.

What is the circumcenter of a scalene obtuse triangle?

In a scalene obtuse triangle, the circumcenter will lie outside the triangle. A scalene triangle can be an obtuse-angled, acute-angled or right-angled triangle. Comparison-Scalene, Isosceles and Equilateral Formulas (Area and Perimeter)

What is the difference between acute and oblique triangles?

Any triangle that is not a right triangle is classified as an oblique triangle and can either be obtuse or acute. In an obtuse triangle, one of the angles of the triangle is greater than 90°, while in an acute triangle, all of the angles are less than 90°, as shown below.

What are the interior and exterior angles of a triangle?

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
