What are 3 characteristics of an obtuse triangle?

Obtuse Angled Triangle Properties

The sum of the two angles other than the obtuse angle is less than 90°. The side opposite the obtuse angle is the longest side of the triangle. An obtuse triangle will have one and only one obtuse angle. The other two angles are acute angles.

What are some characteristics of an acute angle?

An angle with a measurement of less than 90° is called an acute angle. L shape forms 90° so if the arms of an angle open up less than an “L”, an acute angle is formed.

What are the characteristics of angle?

Geometric characteristics of angles

A right angle has a 90° angle measurement. An obtuse angle has a measurement greater than 90° but less than 180°, and a straight angle, which looks like a straight line, has a 180° angle measurement. Two angles are known as congruent angles if they have the same measurement.

How do you describe obtuse?

Definition of obtuse

2a : lacking sharpness or quickness of sensibility or intellect : insensitive, stupid He is too obtuse to take a hint. b : difficult to comprehend : not clear or precise in thought or expression It is also, unfortunately, ill-written, and at times obtuse and often trivial.—

How do you describe an acute and obtuse angle?

An acute angle is one that measures LESS than 90˚. An obtuse angle is one that measures between 90˚ and 180˚. A reflex angle is an angle that measures between 180˚ and 360˚.

What degree is an obtuse angle?

Obtuse angles measure more than 90 degrees.

What are 3 acute angles?

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

What are the examples of acute angle?

An angle which is measuring less than 90 degrees is called an acute angle. This angle is smaller than the right angle (which is equal to 90 degrees). For example, ∠30o, ∠45o, ∠60o, ∠75o, ∠33o, ∠55o, ∠85o, etc. are all acute angles.

Which shows an acute angle?

An acute angle is a type of angle that measures less than 90°. For example, when the time is 11 o’clock, the angle formed between the hour hand and the minute hand is an acute angle. In other words, 30°, 40°, 57°, and so on are all acute angles.

Which of the following shows an acute angle?

The angle that measures less than 90 degrees is called acute angle. Examples: 30°, 45°, 60°, 85° are acute angles.

What is example of obtuse angle?

Some examples of obtuse angle degrees are 110°, 135°, 150°, 179°, 91°, and more. Hence, all angles that lie in the range of 90° to 180° are obtuse angles.

What is the two example of obtuse angle?

Obtuse Angle: An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. Example: 95∘,120∘,130∘,etc.

What objects have obtuse angles?

Some other examples of obtuse angles in real-life are given below: The angle between the hour and minute hand of a clock at 4 o’clock. The angle between the base of an open laptop and its screen. Angles formed by the blades of a ceiling fan.

Is an obtuse angle perpendicular?

Which of the following measures describes an obtuse angle?

An obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees.

How do you tell if a triangle is acute or obtuse?

An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.

What defines an obtuse triangle?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.

Which of the following is an obtuse?

Solution; Obtuse angle is defined as an angle whose measure is between 90° and 180° In other words,t can be said that an obtuse angle is an angle which lies between a right angle and a straight angle.
