2.0) Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raisiing to a fractional power. They understand the rules of exponents.
1) Students know what is a right triangle, its legs and its hypotenuse.
2) Students can solve for the hypotenuse given the length of the legs.
3) Students can solve for the length of one of the legs given the lenght of the other leg and the hyponuse.Student Activities
Students are provided 3 images which have of right triangles inside of them.The right triangles are highlighted. The legs and hypotenuse are labeled.
1) in a street map
2) in a pyramid
3) in a baseball diamond
The students are assigned to search the internet for more images that have right triangles in them. They can print out the images and highlight the right triangles. They should also label the 2 legs and the hypotenuse.
