Can the altitude to the base of an isosceles triangle be longer than the leg of the triangle?

whitemonsterbunny17 (whitemonsterbunny17):

Please explain with a diagram. Thanks! \(\Large\color{magenta}{\heartsuit}\)

jimthompson5910 (jim_thompson5910):

this is a right triangle?

whitemonsterbunny17 (whitemonsterbunny17):

It is an isosceles triangle. No other information is given.

jimthompson5910 (jim_thompson5910):

here are 2 examples of isosceles triangles |dw:1421639940948:dw|

jimthompson5910 (jim_thompson5910):

draw in the altitude or height |dw:1421639994056:dw| does the height look longer than the congruent legs?

Miracrown (miracrown):

|dw:1421640019989:dw| I have drawn an isosceles triangle and as you can see the altitude is greater than the base there are not restrictions for it

whitemonsterbunny17 (whitemonsterbunny17):

@jim_thompson5910 Not on all of them, no.

Miracrown (miracrown):

2 different situations, where the altitude to the base is greater and lower than the base

whitemonsterbunny17 (whitemonsterbunny17):

So it could be longer?

jimthompson5910 (jim_thompson5910):

focus on this right triangle |dw:1421640144097:dw|

jimthompson5910 (jim_thompson5910):

the leg of the isosceles triangle is now the hypotenuse of that triangle I highlighted

whitemonsterbunny17 (whitemonsterbunny17):

I'm not getting it.. is it longer?? o-O

jimthompson5910 (jim_thompson5910):

the hypotenuse is always the longest side

jimthompson5910 (jim_thompson5910):

so the altitude of the isosceles triangle is never longer than the leg of the isosceles triangle

whitemonsterbunny17 (whitemonsterbunny17):

Never? No matter the size?

jimthompson5910 (jim_thompson5910):

correct, the altitude is either equal to the leg or smaller than the leg it's only equal to the leg when we have an isosceles right triangle

whitemonsterbunny17 (whitemonsterbunny17):

Okay, that makes sense, now.. \(\Large\bf\color{magenta}{\bigstar~}\color{blueviolet}{Thanks!~}\color{magenta}{~\bigstar}\)
