Done Discovery EXPAND Prior to completing the construction and discovery for Triangle Construction and Discovery, you may need to review how to construct triangles with students This lesson provides scaffolded notes and websites which can be used as review tools Also, a quick review using this applet may help to remindQ Find x the length of the hypotenuse of the triangle Q Find a the length of the hypotenuse Q If the leg of a triangle is 7 cm long, then its hypotenuse is _____ cm Q Find the value of y Q Find the value of y Q Find the value of y Q Find a the length of a leg of the triangleThe toughest thing for many students is to tell the and triangles apart based on their side lengths So, in this video I introduce you to both the fractions and nonfractions versions of these "special" triangles, and I show you tricks to keep the two straight (TIP 90% of the time, if there's a "3" under the square root it's a 3060, and if there's a "2" under any root it's a 4545)
