How to use similar triangles to find height
WebUse similar triangles constructed by using a mirror to view the height of the TALL object. SETUP A. Place the mirror on the ground a distance from the TALL object. Make sure you can see to the top of the TALL object in the mirror! B. Now position yourself with the mirror between you and the TALL object so when you look at the mirror Web27 apr. 2024 · Triangles ΔABC and ΔDEC are similar trianglesbecause all three of their corresponding angles are congruent. Therefore, the ratios of their corresponding sides are equal. AB DE = BC EC. AB 6 = BC 10. Let's solve for BC: BC = 10 6 (AB) = 5 3 (AB) BC = 25 ft. (shadow of the building) Let's plug it in: 25 = 5 3(AB)
How to use similar triangles to find height
Did you know?
WebThe height is given by dropping a perpendicular down from one of the vertices of the triangle. Since we are looking at an equilateral triangle, each internal angle is 60 ∘, so by dropping this perpendicular we have … Web3 feb. 2024 · 3. Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle! Example. 20 = 1/2 (4)h Plug the numbers into the equation. 20 = 2h Multiply 4 by 1/2.
