Is obtuse the opposite of acute?
Frequently Asked Questions About obtuse
While all three words mean “not sharp, keen, or acute,” obtuse implies such bluntness as makes one insensitive in perception or imagination.
What is the opposite of an acute triangle?
The opposite of an acute angle is an obtuse angle, which is greater than 90˚.
What is the opposite of acute in math?
In math, the word ‘acute’ refers to an angle less than 90°, or to a shape involving angles less than 90°. It is the opposite of obtuse, which refers to an angle greater than 90°.
What are the 7 types of angles?
What are the 7 different types of angles?
Zero Angle (0° in Measure)Acute Angle (0 to 90° in Measure)Right Angle (90° in Measure)Obtuse Angle (90 to 180° in Measure)Straight Angle (180° in Measure)Reflex Angle (180 to 360° in Measure)Complete Angle (360° in Measure)
What is the opposite of acute mean?
Overview. Acute conditions are severe and sudden in onset. This could describe anything from a broken bone to an asthma attack. A chronic condition, by contrast is a long-developing syndrome, such as osteoporosis or asthma.
What is the opposite of an obtuse angle?
Let’s look at it from another angle. In geometry class we learn about obtuse angles: those are the wide ones, greater than 90 degrees, in contrast to acute angles, which are smaller than 90 degrees. An acute angle makes a sharp point, while an obtuse person is not all that sharp intellectually.
What is brawl opposite?
Opposite of a rough or noisy fight. agreement. calm. harmony.
What is the opposite of 90 degrees?
The hypotenuse is the side of a right triangle that’s opposite the 90-degree angle. It’s a term specific to math, specifically geometry. Hypotenuse comes from the Greek word hypoteinousa which means “stretching under.” The hypotenuse “stretches under” the right angle of a triangle, which has an angle of 90 degrees.
What is an oblique triangle?
An oblique triangle is any triangle that is not a right triangle. It could be an acute triangle (all threee angles of the triangle are less than right angles) or it could be an obtuse triangle (one of the three angles is greater than a right angle).
What is reflex of an angle?
A reflex angle is any angle that is more than 180 degrees (half circle) and less than 360 degrees (full circle). A reflex angle will always have either an obtuse or an acute angle on the other side of it.
What is a supplementary angle?
Definition of supplementary angles
: two angles or arcs whose sum is 180 degrees.
What type of angle is 180 degrees?
Angles between 90 and 180 degrees (90°
What is the vertically opposite angle?
When two lines intersect, the opposite (X) angles are equal. In the diagram above, the two green angles are equal and the two yellow angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex.
Are co interior angles?
Co-interior angles occur in between two parallel lines when they are intersected by a transversal. The two angles that occur on the same side of the transversal always add up to 180º . We can often spot co-interior angles by drawing a C shape. The two interior angles are only equal when they are both 90º.
