Can a triangle have both an obtuse and right angle?

Can a triangle have both an obtuse and right angle?

No, a triangle cannot have an obtuse and a right angle.

Why is it not possible to have a triangle with two obtuse angles?

Give reason for your answer. 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 right triangle ever obtuse?

An obtuse angle is one that measures more than 90°. A right triangle has a 90° angle. The sum of the three angles of a triangle equal 180°. A triangle cannot have two 90° angles, there an obtuse triangle is NEVER a right triangle.

Why can’t a triangle be obtuse and right?

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.

Can a triangle have 1 obtuse angles?

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.

What is the greatest number of obtuse angles a triangle can contain?

1 obtuse angle
A triangle can have a maximum of 1 obtuse angle.

Does a triangle have to have 3 equal sides?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

What does a right obtuse triangle look like?

A right triangle has one angle that’s 90° and a corner that looks like an L. Obtuse triangles have one angle that’s greater than 90°. In acute triangles, all the angles are less than 90°.

Can 1 acute and 2 obtuse form a triangle?

Types of Triangles. All equilateral triangles are equiangular. A right triangle will have 1 right angle and 2 acute angles. An obtuse triangle will have 1 obtuse triangle and 2 acute angles.

What is a uneven four sided shape called?

irregular quadrilateral
What is an irregular quadrilateral? Irregular quadrilaterals are: rectangle, trapezoid, parallelogram, kite, and rhombus. They are symmetrical, but are not required to have congruent sides or angles.

Is any 4 sided polygon a triangle?

After triangles, the type of shape we will encounter the most is the quadrilateral: Quadrilateral : A polygon with four sides….Polygons in General.
