How many acute angles are in an obtuse triangle?
two acute angles
Explanation: An obtuse scalene triangle must have one obtuse interior angle and two acute angles. All triangles have three interior angles with a sum total of degrees.
Can a triangle have a 2 acute angles?
The definition of acute angle is that the range for the angle has to be 0∘<α<90∘. Therefore, a triangle can have two acute angles as the sum of those two angles becomes less than 180∘.
Does an obtuse angle have acute angles?
There are exactly two acute angles in an obtuse triangle, where an acute angle is an angle with measure less than 90°.
Can a triangle be both acute and obtuse?
Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It’s impossible for a triangle to have more than one obtuse angle.
What kind of triangle has one obtuse angle and two acute angles?
obtuse triangle
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
Why a triangle Cannot have more than one obtuse angle?
Two obtuse angles by definition mean that there would be two angles of (at least) 91 degrees each. Therefore, a triangle can never have more than one obtuse angle. When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle.
Which shape has both acute angles and obtuse angles?
A trapezoid is a parallelogram with one pair of opposite sides parallel. Here is an example of a trapezoid. Notice that this trapezoid has two acute angles and two obtuse angles.
Can one obtuse angle and one acute angle be complementary to each other?
Answer : No, one acute angle and one obtuse angle cannot be complementary to each other because obtuse angles themselves are greater than 90°.
Can a triangle have more than one 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. Which triangle do not have an obtuse angle? Why a triangle Cannot have more than one obtuse angle?
How many acute and right angles are in a triangle?
How many acute obtuse and right angles are in a triangle? right angles (exactly 90°) obtuse angles (more than 90°, less than acute angles (less than 90°) Right triangles have exactly one right a Obtuse triangles have exactly one obtuse Acute triangles have three acute angles.
What’s the difference between an acute and an obtuse angle?
Angles between 0 and 90 degrees (0°< θ <90°) are called acute angles. Angles between 90 and 180 degrees (90°< θ <180°) are known as obtuse angles. Angles that are 360 degrees (θ = 360°) are full turn.
What does the word obtuse mean In geometry?
Obtuse comes from a Latin word meaning “blunt, dull, stupid.” “Obtuse angles” in geometry are not stupid; they are blunt. An angle “greater than 90 degrees and less than 180 degrees” is an obtuse angle. When applied to a person, obtuse means stupid, lacking in perception or understanding.
