What Is The Greatest Number Of Obtuse Angles In A Triangle?

Can you have a triangle with two right angles?

Answer and Explanation: Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles..

Which shape has no line of symmetry?

What is the order of rotational symmetry?

The order of rotational symmetry of a shape is the number of times it can be rotated around a full circle and still look the same. If the triangle is rotated a full 360°, it never looks the same except when it arrives back at its original starting position.

Can a triangle have 2 obtuse angles?

No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.

How many obtuse angles does a scalene triangle have?

(2 acute angles) An obtuse scalene triangle. This is very similar to the right scalene triangle, except it has one angle whose measure is greater than 90˚ , and two acute angles.

Can a triangle have one obtuse and right angle?

No, a triangle cannot have an obtuse and a right angle. … The sum of the angles of…

Can a triangle have all angles equal?

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

Why can a triangle only have one right angle?

Explanation: Since the sum of all angles in any triangle is equal to 180o , so there can be only one right angle if all other angles are to be greater than zero. So the angle C would have to be zero, which is impossible.

Can a triangle have 3 obtuse angles?

Triangle cannot have more than one obtuse angle because there are 3 side and if you add three sides it equals to 180 degree and obtuse angle is greater than 90 degree and the other two has to be less than 90 degree. … By definition, the sum of angles of a triangle is 180 degrees.

Which shape has the greatest number of angles?

chiliagonIn geometry, a chiliagon (/ˈkɪliəɡɒn/) or 1000-gon is a polygon with 1,000 sides.

Can a triangle have all angles more than 60 degree?

A triangle cannot have neither all the angles less than 60 degree nor greater than 60 degrees. All the angles in a triangle can never be less than 60 nor greater than 60. However all the angles can be acute ,whether only two of them.

What is the greatest number of right angles in a triangle?

Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .
