minus-squareCoskii@lemmy.blahaj.zonelinkfedilinkarrow-up54arrow-down5·30 days agoI hated pictures like this in school. The numbers are just slapped on an inaccurate image and somehow they expect people to ignore the obvious right triangles and just focus on the math part of it.
minus-squareSchmidtGenetics@lemmy.worldlinkfedilinkarrow-up15arrow-down3·30 days agoIf it was to scale you could just use a protractor and skip the whole math part, which is the entire part of the lesson…
minus-squareCoskii@lemmy.blahaj.zonelinkfedilinkarrow-up9arrow-down2·30 days agoI don’t see that as a downside as long as these two questions are also included. How many degrees make up the inner angles of a triangle? How many degrees make up one side of a straight line?

minus-squarePacattack57@lemmy.worldlinkfedilinkarrow-up6arrow-down3·30 days agoAnd what’s wrong with that. Utilizing real world solutions to problems is a life skill. Not some obscure formula that you will forget anyway.

minus-squarenul9o9@lemmy.worldlinkfedilinkarrow-up3·30 days agoI was scared I forgot basic trig stuff.
