Which triangle has the same area as triangle ๐ฟ๐ต๐ถ?

So here is triangle ๐ฟ๐ต๐ถ. It would be triangle ๐ท๐‘‹๐ฟ and not just because it looks like it. Hereโ€™s the reasons why. They share the same vertex at ๐ฟ. And they have equal base lengths and we know that because of these markings. But itโ€™s important to add that the equal base lengths must lie along the same line. This is because if theyโ€™re on the same line and they meet at the same vertex, then their heights must be equal.

And this is important because the area of a triangle is equal to one-half times the base times the height. And if they have equal bases and equal heights, their areas must be exactly the same.

So once again, the triangle that has the same area as triangle ๐ฟ๐ต๐ถ would be triangle ๐ท๐‘‹๐ฟ.
