Question

Help with this geometry????

Answer 1

2. Given (perpendicuar makes right angles)
3.
4. SHT =~ STD
5. simplify

Answer 2

how'd you get that?

Answer 3

I'm sorry my brains scrambled right now haha.

So:

2. This is true because SD ┴ HT, so from the definition of perpendicular lines those two angles are right angles

3. Was given at the top

4. Side SD is a side common to both triangles, so it's the same for both of them

5. We have side SH = ST, side SD = SD, and a right angle on both triangles, so by SAS congruence the two triangles are congruent.

Sorry bout that. Hope I helped :P
