1. Dentro de tu hogar escoge cinco objetos que tengan forma rectangular o cuadrada, mide con un metro o regla su base y su altura luego la diagonal del objeto. Cada una de estas medidas las vas a registrar en la siguiente tabla.

Luego halla la hipotenusa (diagonal) de cada objeto aplicando la fórmula del teorema de Pitágoras.

APARATO BASE ALTURA DIAGONAL (Hipotenusa) Hipotenusa usando teorema de Pitágoras ​

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
