What is a triangle with all acute angles and exactly two congruent sides?
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o. Remember that the SUM of the angles in a Triangle must equal 180o.
Is a triangle with sides 10 14 10 obtuse acute or right?
it is an acute triangle.
Can a right triangle have two acute angles?
A right angled triangle can only have two acute angles.
What is an acute equilateral triangle?
An equilateral triangle must be acute because each angle is equal to 60 degrees. If all three angles are less than 90 degrees then a triangle is acute.
How many acute sides does an acute triangle have?
First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
The definition and example of an acute triangle?
An acute triangle is also known as a scalene triangle that has 3 sides of different lengths and 3 interior acute angles of different sizes
Do all the angles in an acute triangle have to be different?
No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
What is the definition for an acute triangle?
An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.
What is the definition of acute polygons?
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
Is there such thing as an acute right triangle?
Yes, an acute right triangle is a bit of a misnomer, as a right triangle by definition has one angle that is exactly 90 degrees. This means that the other two angles must be acute (less than 90 degrees), making the triangle a right triangle but not acute overall. Therefore, while it can have acute angles, it cannot be classified as an acute triangle.
Are all equallateral triangles acute?
-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.
A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
Can a right triangle be acute or scalene or isosceles?
A right triangle may be isosceles or scalene (though not at the same time), but never acute, since an acute triangle is defined as having all interior angles less than 90°. A right triangle by definition has one 90° angle.
How much how much degrees are in an acute triangle?
less than 90 degreesAnswer:The sum of the angles in any triangle are always 180o. By definition an acute triangle is one in which all three angles are acute angles (less than 90o). As soon as one angle becomes 90o (right angled triangle) or greater (obtuse angled) the triangle is no longer acute.
Can a Right triangle also be acute?
No, because a right triangle has one angle which is 90 degrees, and the definition of an acute triangle says that each of the 3 angles of the triangles must be less than 90 degrees.
What does a right acute triangle look like?
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
Is an equilateral always an acute triangle?
Because each of its equal interior angles are less than 90 degrees.
