Egyptians used special right triangles to survey land by measuring out 345 right triangles to make right angles The Egyptians mostly understood right triangles in terms of ratios or what would now be referred to as Pythagorean Triples The Egyptians also had not developed a formula for the relationship between the sides of a right triangle At this time in history, it is important toDAY 3 (58) SWBAT Solve Problems involving Special Right Triangles Pgs 1622 HW Pgs 2325 DAY 4 (Review) SWBAT Solve Problems involving Right Triangles Pgs 2631Figure 1914A 345 triangle Figure 1915Triangles which may be mistaken for 345 triangles can be because the triangle is not a right triangle, as in figure 1915 (A) On the other hand, even though the triangle is a right triangle its longest side may be the 4unit side, in which case the third side cannot be 5 units long (See fig 19

The other common SSS special right triangle is the 5 12 13 triangle We call it the 3 4 5 "ratio" because the side lengths do not need to be exactly 3, 4, and 5, but rather can be any common factor of these numbers For example, a right triangle with side lengths of 6, 8, and 10 is considered a 3 4 5 triangle Its side lengths are a common But the 345 triangle is the layman's substitute for the Pythagorean theorem The 345 triangle is the best way I know to determine with absolutely certainty that an angle is 90 degrees This rule says that if one side of a triangle measures 3 and the adjacent side measures 4, then the diagonal between those two points must measure 5 in order for it to be a right triangle Here, we will learn about 345 right triangles and how to solve problems involving them What is a 345 Triangle A 345 triangle is a special right triangle whose side lengths are in the ratio of 3 4 5 It is thus a right triangle with sides in the ratio of integer lengths (whole numbers) called Pythagorean triples Since all its side lengths are different from the other;
