Scenario with this thing right over here. If it was actually symmetricĪbout the horizontal axis, then we would have aĭifferent scenario. Make, essentially it's going to be an upsideĭown version of the same kite. Now let's think about thisįigure right over here. To the center of the figure, and then go thatĭistance again, you end up in a place where Let's say the center of theįigure is right around here. Or I should say, it willĪround its center. So I think this one willīe unchanged by rotation. Same distance again, you would to get to that point. This point and the center, if we were to go that That same distance again, you would get to that point. Point and the center, if we were to keep going Think about its center where my cursor is right And then if rotate it 180ĭegrees, you go over here. A trapezoid is a quadrilateral with one pair of parallel sides. Rotate it 90 degrees, you would get over here. An Isosceles trapezoid, as shown above, has left and right sides of equal. So what I want you to doįor the rest of these, is pause the video and thinkĪbout which of these will be unchanged andīrain visualizes it, is imagine the center. A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel. I have my base is shortĪnd my top is long. Below we present the generic diagram of the isosceles trapezoid. The bases of an isosceles trapezoid are still parallel, but the legs are of equal length. This means that both base angles are congruent. What happens when it's rotated by 180 degrees. An isosceles trapezoid is a trapezoid in which the legs (non-parallel sides) have the same length. Trapezoid right over here? Let's think about The two parallel sides of the trapezoid are referred to as the bases of the trapezoid the other two sides are called the legs. Square is unchanged by a 180-degree rotation. So we're going to rotateĪround the center. And we're going to rotateĪround its center 180 degrees. One of these copies and rotate it 180 degrees. Were to rotate it 180 degrees? So let's do two Which of these figures are going to be unchanged if I
