Which students, if any, have correctly identified a base and its corresponding height? which ones have not? explain what is incorrect. explain what is correct.

The Explanation is below with correction in the Figure.

Step-by-step explanation:

Height is also call as Altitude.

Height of Triangle always measure in PERPENDICULAR to the Base.

a. )

Raul is correct because Height should always be Perpendicular, and Raul has drawn Height 'h' Perpendicular to the corresponding Base 'b'.

b. )

Mark is incorrect because Height drawn is NOT Perpendicular.

c. )

Kiki is incorrect because the corresponding base is incorrect, Height drawn is correct that is Perpendicular.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
