    1:If oyu know two lengths of a right triangle how do you find the third. 2:Can i find two missing side lengths of a right triangle if i only knew 1 length and one angle, 3:Can i find two missing angles if i knew some of the side lengths of a right triangle. 4:what makes a triangle a special right triangle?how can it being special help me find side lengths?

    to find the hypotenuse: square the lengths of the two legs, and the squares together, then take the square root to find one of the legs: square the length of the hypotenuse, square the length of the leg you know, subtract that number from the square of the hypotenuse, take the square root

    1. You can find any side of a right triangle of a right triangle if you know two of the sides by using the pythagorean theorem. The pythagorean theorem is c^2=a^2 + b^2. In this equation a and b and the lengths of the sides that form the right angle. c is the long side which is called the hypotenuse.

    Create a unique teaching example to demonstrate what you explained in words. Work through this example step by step. Create a unique practice example. Provide the problem and the answer. Because you'd like your friend to show their understanding of what you taught, make the practice example different from the teaching example. For example, if the teaching example for #1 was missing the hypotenuse, have the practice example missing one of the legs. Or, if the teaching example for #4 used the sin ratio, have the practice example use the cosine or tangent ratio.

    Here we can find the missing leg, b, by saying 6^2+b^2=10^2 36+b^2 = 100 b^2=64 b=8 So the missing leg is 8 Now you try this one: |dw:1326917349832:dw|

    so is this good for number 1 you think? 1. You can find any side of a right triangle if you know two of the sides by using the Pythagorean Theorem. The Pythagorean Theorem is c^2=a^2 + b^2. In this equation a and b and the lengths of the sides that form the right angle. c is the long side which is called the hypotenuse. An example could be if the length of one leg in a triangle is 3 and the other is 4, then do 3^2+4^2=C^2. So 9+16=25. Then you take the square root of 25, and you get your hypotenuse which would be 5. Example: Here now you try this one. I have a right triangle which has one leg equal to 6. The other leg is missing but I know the hypotenuse is 10. The answer is 13 but can you try and solve this?

    2:Can i find two missing side lengths of a right triangle if i only knew 1 length and one angle, Yes. You can find the missing sides if you know one side and one angle. You can use the trig function that involves the side of the triangle that you know and the side of the triangle that you are trying to find.

    The sin function is the side opposite the known angle divided by the hypotenuse. The cos function is the side adjacent the known angle divided by the hypotenuse. The tan function is the side opposite the known angle divided by the side adjacent.

    Start with the acute angle that you know. Identify the known side in relation to that angle. Then identify the side that you want to find. Choose the appropriate function and substitute the values. For example if you know the angle is 30 degrees and you know the side opposite the 30 degree angle is 10 and you want to find the hypotenuse then use the sin function. Write sin 30 = 10/h and solve that equation. .5=10/h .5h=10 h=20 Now you try this one: In a right triangle there is a 45 degree angle. The hypotenuse is 10. Find the side adjacent to the 45 degree angle. The answer is 7.07. See if you can get it.
