Page 166 - The sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.
Page 166 - The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
Page 83 - If two sides of a triangle are unequal, the angles opposite are unequal, and the greater angle is opposite the greater side.
Page 170 - If two polygons are composed of the same number of triangles, similar each to each and similarly placed, the polygons are similar.
Page 105 - A tangent to a circle is perpendicular to the radius drawn to the point of contact.
