You ask your students to draw a triangle with side lengths of 4 cm, 2 3/4 cm, and 1 3/4 cm and then identify potential pairs of bases and heights for the triangle.  Below is an image featuring six different base/height pairs identified by the students.  Select the ones that show an actual combination of base lengths and corresponding heights for the triangle. Figure A long description (click to reveal) Side length of 4 cm noted with perpendicular line from that side to the other vertex marked as h.   Figure B long description (click to reveal) Side length of 2 3/4 cm noted with perpendicular line outside the triangle from that side to the other vertex marked as h.   Figure C long description (click to reveal) Side length of 2 3/4 cm noted with side length connecting that length to the other vertex is marked h.   Figure D long description (click to reveal) Side length of 1 3/4 cm noted with side length connecting that length to the other vertex is marked h.   Figure E long description (click to reveal) 90 degree angle formed with dotted lines outside the triangle with one of the lines marked as 2.2 cm and the other marked as h.    Figure F long description (click to reveal) Side length of 1 3/4 cm noted with perpendicular line outside the triangle from that side to the other vertex marked as h.
