@ParthKohli @paki @mathmate @Miracrown please help me understand. Im stuck between C & D :(
Can you post or draw the diagram, according to the given information, and start from there? In geometry, a diagram must be drawn, if it is not already supplied. Drawing the diagram by hand will help you sort out the given information. With practice, most simple problems will be solved when you finish drawing the diagram.
Can you explain "by HL".
is HL hight and length?
Have you drawn the diagrams?
Once you have done that, you can determine which sides are the heights and which are the lengths. And the problem will be solved.
im having trouble trying to draw it, i cant place the sides where they belong. my brain keeps mixing things up . :(
@Directrix @Nnesha @zepdrix
That doesn't sound good for someone working on geometry. I believe the first lesson in geometry is to follow instructions/information to draw a diagram. I'll start the drawing and let you complete. Question wants you to prove ΔABC≅ΔXYZ, and angle B=90. so as we discussed before, the angles must be listed in order. |dw:1444075556282:dw| Now read the question again, and fill in all information not already in the diagram. After that, you can decide which of the missing information is required to prove by HL.
b= 90 degrees y= 90 egrees BC= 20 in length YZ= 20 in length AC=XZ correct?
@mathmate i think D would be my answer, i just checked it with my other options and none of them match up except for D :3
Can you draw the information on the diagram, after which you will not make the mistake you just made?
ok ill try, im using a mouse ll
@mathmate i used the writing tool but
i hope it makes enough sense
That's good. It seems that the notion of "height" is not clear to you. Height in a figure is the length measure perpendicular to the base. For example, |dw:1444076849602:dw| You will see that the slant side is not a height. Only the perpendicular distance is.
so if its slanted/diagnal its called a perpendicular distance? @mathmate
"Height in a figure is the length measure perpendicular to the base." If it is not perpendicular to the base it is not a height. Think of what you measure when you measure the height of a building. You would not measure it on the slant.
OHHHHHHHHHHHH ok so id compare measuring the height of a regular building to the leaning tower of pizza?
now that you know what the length (BC) and height. You know what additional information you would need to complete the proof.
yes!~ thank you VERY VERY much for having SO SO SO much patience with me! im really slow sometimes @mathmate
You're welcome! :)
