Question

One teaching example for each of the four questions, which includes step by step instructions written in complete sentences.

If I know the lengths of two sides of a right triangle, how do I find the third?
Could I find the two missing side lengths of a right triangle if I only know one side length and one angle measure (other than the 90 degree angle)?
Could I find the two missing angle measures if I know some of the side lengths of a right triangle?
What makes a triangle a “special” right triangle? How can special right triangles help me find side len

Answer 1

1) by using heron's formula..

Answer 2

2) yes, by using phythagoreas theorm.

Answer 3

3) by applying theorm- no side is required you can find it by using angle sum property.

Answer 4

4) by phythagoreas thoerm...

Answer 5

@pumpgirls

Answer 6

what?

Answer 7

oh now i get it can u please explain more on the 4 questions

Answer 8

il answer the last part of question - what makes a triangle special

do you knw the two special triangles ?

Answer 9

no i dont .
you cant help me with the other three

Answer 10

As for the first one, to my understanding, Heron's formula is actually used to find the area of triangle. It can't be the answer to the first question.

Answer 11

oh ok then do u have an idea of the what the answer would be for question 1 ?

Answer 12

Have you ever heard of trigonometric ratios and Pythagoras' Theorem?

Answer 13

yes

Answer 14

What do you know about them, for example, the conditions when the ratios or the theorem is applied?

Answer 15

yea

Answer 16

So, what's the condition when Pyth. Thm is applied?

Answer 17

im not sure

Answer 18

let a be any angle given in triangle then side opposite to a is called as perpendicular(p) , side opposite to 90 deg angle is called as hypotenuse(h) and remaining side is base(b) tan a =(p/b) sin a =(p/h) cos a =(b/h)

Answer 19

ok how do i do that tho?

Answer 20

@pumpgirls Sorry I wasn't here for a while. Do you know that you can get the relation a^2 + b^2 = c^2 when the triangle is a right-angled triangle, according to the Pyth Thm?

Answer 21

yes

Answer 22

So, if you have two sides, do you think you can apply this theorem to find the third, provided that it's a right-angled triangle.
