What is the area of an equilateral triangle with sides of 10 inches and height of 7?
The area of an equilateral triangle with sides of 10 inches and height of 7 inches is 35 sq. in. Area =1/2 *b*h =1/2 *7*10 =35 sq.
What is the area of the triangle below?
Triangle area formula area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
Which type of triangle has one angle with a measurement greater than 90?
obtuse triangle
An obtuse triangle is a triangle in which one of the interior angles is greater than 90°. It has one of its vertex angles as obtuse and other angles as acute angles i.e. when one angle measures more than 90°, the sum of the other two angles is less than 90°.
Which type of triangle has one angle?
right-angled triangle
A right-angled triangle has one 90° angle. That 90° angle is shown as a small square where two sides of the triangle join. It is possible for a triangle to be a right-angled triangle and an isosceles triangle at the same time.
How do you find the area of a equilateral triangle with height?
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.
How do you find the height in a triangle?
Triangle height, also referred to as its altitude, can be solved using a simple formula using the length of the base and the area.
- h = 2Tb.
- s = p2.
- h = abc.
- ha = √(a² – (0.5 × b)²) × ba.
- h = a × √32.
What is an obsolete triangle?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.
What triangle has all three angles measuring less than 90?
Acute Triangle
Vocabulary

| Equilateral Triangle | An equilateral triangle is a triangle in which all three sides are the same length. |
| Obtuse Triangle | An obtuse triangle is a triangle with one angle that is greater than 90 degrees. |
How many types of triangles are there in class 9?
According to the lengths of their sides, triangles can be classified into three types which are: Scalene. Isosceles. Equilateral.
What is height of equilateral triangle?
Formula to calculate height of an equilateral triangle is given as: Height of an equilateral triangle, h = (√3/2)a, where a is the side of the equilateral triangle.
