Grade 6

Practice

1. Problem 1

   Student Task Statement

   Select all drawings in which a corresponding height for a given base is correctly identified.

   

   An image of a triangle labeled A. The top side of the triangle is labeled, b, and a dashed line labeled, h, extends straight down from the right vertex. 

   

   The triangle top side is labeled “b” and a dashed line labeled, h, extends from the center of the top side to the opposite vertex. 

   

   A triangle labeled C. The right side of the triangle is labeled, b, and a dashed line extends from the left top vertex straight down to the level of the bottom vertex labeled, h.

   

   A triangle labeled D. The left side of the triangle is labeled, b, and a perpendicular line labeled, h, extends to the opposite vertex.

   

   A triangle labeled E. The left side of the triangle is labeled, b, and a dashed line labeled, h, extends out from the bottom vertex at a right angle to the right side. 

   

   A triangle labeled F. The right side of the triangle is labeled, b, and a perpendicular dashed line labeled, h, extends from the side labeled, b, to the opposite vertex.
