## What does a acute mean in math?

An acute angle is an angle that measures between 90° and 0°, meaning it is smaller than a right angle (an “L” shape) but has at least some space between the two lines that form it. Acute angles are a basic concept of geometry with big applications.

## What is an example of a acute?

Acute is defined as something that is very serious, severe or extreme. An example of the word acute would be when you fall and hurt your wrist resulting in breakage or fracture. This would be considered acute wrist pain as it came on quickly, is severe and will likely subside relatively quickly.

## What does acute mean in triangles?

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 shapes are acute angles?

You can find acute angles as exterior angles in shapes with five or more vertices like pentagons and octagons. You can also find acute angles as interior angles in rhomboids and triangles. Consider the isosceles and equilateral triangles, which depend on two and three acute angles for their construction.

## What does acute mean in math for kids?

acute angle. • an angle measuring less than 90 degrees. EXAMPLE: 45º

## What does obtuse mean in math?

2 mathematics: not ending in a sharp point: measuring between 90 degrees and 180 degrees an obtuse angle.

## Does acute mean extreme?

acute adjective (EXTREME) very serious, extreme, or severe: The area has an acute water shortage. 6

## Does acute mean sharp?

sharp or severe in effect; intense: acute sorrow;an acute pain. sharp or penetrating in intellect, insight, or perception: an acute observer.

## Does acute mean short term?

Acute often also connotes an illness that is of short duration, rapidly progressive, and in need of urgent care. “Acute” is a measure of the time scale of a disease and is in contrast to “subacute” and “chronic.” “Subacute” indicates longer duration or less rapid change.

## Which triangle is acute?

An acute triangle is a triangle in which each angle is an acute angle. Any triangle which is not acute is either a right triangle or an obtuse triangle. All acute triangle angles are less then 90 degrees. For example, an equilateral triangle is always acute, since all angles (which are 60) are all less than 90.

## Do acute triangles add up to 180?

An acute triangle is a type of triangle hence sum of its interior angles add up to 180 degrees, where each individual angle measures less than 90 degrees.

## Is there an acute right triangle?

A triangle where all three internal angles are acute (less than 90 degrees). Less than 90° – all three angles are acute and so the triangle is acute. Exactly 90° – it is a right triangle.

## What is acute angle example?

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.

## What is an obtuse angle look like?

What does an Obtuse Angle Look Like? The angles measuring greater than 90° and less than 180° are called obtuse angles in geometry. The obtuse angle lies between 90° and 180° and looks like a reclined chair, an angle below the staircase, or an angle formed between a minute and an hour hand of a clock at 10:15 AM.
