What triangle has sides that measure 9 in 9 in and 9 in?

The triangle with sides measuring 9 inches, 9 inches, and 9 inches is an equilateral triangle.


What will be the area of an equilateral triangle if all it's sides are tripled?

It will be 9 times as large. And that will be true for any plane shape, not just an equilateral triangle.


Area of an equilateral triangle with a 9 inch perimeter?

3.897 square inches.


What is the area of an equilateral triangle with a height of 9 inches?

Its area is 46.8 (46.76533) square inches.


How do you find area of triangle with base 10 feet and altitude 9 feet?

Area of a triangle = 1/2*base*altitude in square units Area = 45 square feet


What is an equilateral triangle if each side is 9 meters?

An equilateral triangle with sides of 9 meters, silly!


What is the area of an equilateral triangle if the coordinate points -2 9 and -7 -3 are the same distance apart as the height of the equilateral triangle?

If: (-2, 9) and (-7, -3) is the same distance then the height of the triangle is 13 units and each length of the equilateral triangle is 15.011107 units. Area = 0.5*13*15.011107 = 97.572 square units to 3 decimal places


What is the length of an altitude of an equilateral triangle with a side length of 9 inches?

Use Pythagoras' theorem: 92-4.52 = 60.75 and the square root of this is the altitude which is 7.794 inches to 3 d.p.


If each side of the equilateral triangle measures 9c find the height of the triangle?

The area of a triangle is one-half the product of the triangle's base and height. The height of an equilateral triangle is the distance from one vertex along the perpendicular bisector line of the opposite side. This line divides the equilateral triangle into two right triangles, each with a hypotenuse of 9c and a base of (9/2)c. From the Pythagorean theorem, the height must be the square root of {(9c)2 - [(9/2)c]}, and this height is the same as that of the equilateral triangle.


What is the length of the altitude of an equilateral triangle if one side has a length of 6 cm?

6 squared = 3 squared + x squared if x is the height (altitude) of the triangle 36 = 9+x squared x squared =27 so x = 3 sqrt3 = 5.19615


If each side of an equilateral triangle is 9 cm and you must find the height how would you solve in pythagorean theorem?

Divide the base in half and draw the median from the apex. This median is also the altitude and so its length is the required height. Also, since it is the altitude, it forms a right angled triangle. Using Pythagoras on this triangle, the height is 9*sqrt(3)/2.


What kind of triangle has sides with lengths 9 9 and 9?

An equilateral triangle has three sides of equal length.
