能画出并识别点、直线、线段、射线、角（直角、锐角、钝角）以及垂直和平行线；能在平面图形中辨认这些元素。

Draw and identify points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines; identify these in two-dimensional figures

学习证据 / Evidence

• 指出梯形中所有互相平行的边
• 在给定图形中标出一个直角、一个锐角和一个钝角

• Draw a pair of perpendicular lines and a pair of parallel lines
• Identify all pairs of parallel sides in a trapezoid
• Mark a right angle, an acute angle, and an obtuse angle in a given figure

评估问题 / Assessment

如果给{{name}}一张纸和一把直尺，{{name}}能画出一条线段，标出一个点，然后经过这个点再画一条与第一条线段完全平行的直线吗？

If {{name}} is given a piece of paper and a ruler, can they draw a line segment, mark a point, and then draw another line through that point that runs perfectly parallel to the first?
