• 1. CD has an ,arrow at both ends,, so we pick the diagram showing that ,CD is a line segment,.
,
• 2. CD has an ,arrow at only one end, showing that ,it is a ray,. The corresponding diagram is that which has only one arrow in the same given direction.
,
• 3. In three-letter naming notation for angles, the ,vertex ,of the angle is always the letter in the middle. Thus, for angle CTM, ,the vertex must be at T,. The corresponding diagram is selected below.
The correct pairs formed by the tiles is given below:
