## How do you draw an obtuse scalene?

Construction

- Draw a horizontal line segment from point to by a ruler.
- Use protractor and mark a point at an obtuse angle.
- Take a compass and set it to any length by a ruler.
- Finally, join the points and by a line for completing the construction of a triangle geometrically.

## Can a scalene be obtuse?

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

## Can a triangle be obtuse?

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.

## How do you draw a scalene triangle without a compass?

However, if you do not have a compass, you can draw the triangle without using the circle guide by measuring each side carefully with a ruler. Because each angle is related to the length of the sides as described by the Law of Cosines, when all the sides are equal, all the angles will also be equal.

## What properties exist in an obtuse scalene triangle?

The properties of the triangle are:

- The sum of all the angles of a triangle (of all types) is equal to 180°.
- The sum of the length of the two sides of a triangle is greater than the length of the third side.
- In the same way, the difference between the two sides of a triangle is less than the length of the third side.

## Do obtuse triangles add up to 180?

## Are all the obtuse angled triangles are scalene?

An obtuse triangle is a triangle in which one of the interior angles is greater than 90°. An obtuse triangle can also be called an obtuse-angled triangle. In general, an obtuse triangle can be a scalene triangle or isosceles triangle but not an equilateral triangle.

## Can an obtuse triangle be equilateral?

Since an equilateral triangle has equal sides and angles, each angle measures 60°, which is acute. Therefore, an equilateral angle can never be obtuse-angled. A triangle cannot be right-angled and obtuse angled at the same time.
