The two triangles shown are similar triangles. Numerically, the ratio computed by dividing the length of any side of tower triangle by the length of the corresponding side of the walking stick (similar) triangle will be the same value. Therefore, when the length of the tower shadow is divided by the length of the walking stick shadow, that ratio will be the exactly same as the tower height divided by the walking stick height. (length of tower shadow)/(length of walking stick shadow) = (tower's height)/(walking stick height) tower's height = {(length of tower shadow)/(length of walking stick shadow)}*(walking stick height)
Two triangles are similar. Find the values of x and y when the height is 6.5 and base is x on the first triangle second triangle the height is 26 and base is y. area is 7.8 and could belong to either?
Their values are: x = 2.4 and y = 0.6 which is a ratio of 4 to 1 and both triangles have an area of 7.8 square units
What is a triangle with height called?
All triangles have a height because the area of any triangle is 0.5*base*perpendicular height
Are two triangles congruent if they have same area?
Not necessarily. You find the area of a triangle with the formula 1/2*base*height=Area. Imagine two triangles, one with 3 inches for both the base and height, and one with 4.5 inches for the height and 2 inches for the base. Both of these triangles will have 9 sq. in. for their areas, but they are not congruent.
What is the formula for calculating area of triangles?
Half of the base times height.
What is an objects height measure of?

Which is the height of the triangle?
As for all objects, vertically measure it.

What helps you to measure the height of very tall objects?
trigonometry
How do you measure the volume of irregular floating objects?
To do this, you will need to measure the length and the width and the height and your have your answer to the volume.
How can you recognize similar figures?
They have the same measure of base and height.
Who uses a hipsometer?

How did ancient people checked the height of the pyramids?
Thales of Miletos is the ancient Greek philosopher/ mathematician who first calculated the height of the Great Pyramid of Giza with the use of trigonometry and similar and right triangles.
How do you measure volume of regular objects?
Find length, width, and height. Then you would proceed to multiply all three numbers and there you have your answer.
How do you find out the height of a triangle if only the 3 angles are given?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).

21.6 meters
