What are some real life examples of obtuse angle?

A real life example of an obtuse angle is the front face of a stop sign. The front face of a stop sign is a shape known as a regular octagon.

What is an example of an obtuse?

The definition of obtuse is someone who is slow to understand things. An example of obtuse is someone who listens to a joke but doesn’t understand the punchline. The definition of obtuse is something that isn’t sharp. An example of obtuse is a child’s pair of scissors.

What is an obtuse angle in a house?

Many roof trusses show a visible obtuse angle. The ordinary house has a low ridge roof and the peak of the roof creates an obtuse angle. This is the most common type of truss in many areas, mostly due to its practicality. Right and acute angle trusses create an unusual shape compared to that of an obtuse angle.

What is an obtuse angle give two examples?

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

Is a clothes hanger an obtuse angle?

A coat hanger as well as the angle of a roof creates an obtuse angle, because they both contain an obtuse interior angle.

Can a quadrilateral have 4 obtuse angles?

A quadrilateral cannot have four obtuse angles. An obtuse angle is one which measures greater than 90 degrees and less than 180 degrees.

What are some real life examples of acute angles?

Here are some real-life examples of acute angles.

• A slice of watermelon, when cut in small portions as shown below.
• Some instances of the angles formed between the hour’s hand and the minute’s hand of a clock.
• The beak of a bird when it is open.
• The angle is formed when a crocodile’s mouth is open.

What is an example of a obtuse triangle?

If one angle is greater than 90° and the other two angles are lesser along with their sum being lesser than 90°, we can say that the triangle is an obtuse triangle. For example, ΔABC has these angle measures ∠A = 120°, ∠A = 40°, ∠A = 20°. This triangle is an obtuse triangle because ∠A = 120°.

How many obtuse angles does a triangle have?

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.

How many obtuse angles does a parallelogram have?

two Obtuse Angles
Hence, we can say that a parallelogram has two Obtuse Angles. Note: You can use a protractor to check that the measure of the obtuse angles of a parallelogram. Note that the obtuse angle is greater than 90° and the acute angle is less than 90°.

Is a coat hanger an obtuse angle?

A coat hanger as well as the angle of a roof creates an obtuse angle, because they both contain an obtuse interior angle. ASA postulate is when two angles and a side are congruent.
