16. ̅̅̅. a. 1 point: Student accurately draws a line segment perpendicular to 𝐉𝐊 Responses may vary. Check student work. (See sample response on the next page.) 4.G.1 b. 2 points: Student accurately forms a triangle (size and orientation may vary, but it must be a right triangle) and correctly classifies it by side and angle. Responses will vary. Check student work. (See sample response on the next page.) 4.G.2 c. 2 points: Student correctly identifies whether the triangle has a line of symmetry and accurately explains why the triangle does or does not have a line of symmetry.

Sample responses:
right isosceles
right scalene
Yes, my triangle has a line of symmetry. If it is folded along the dotted line, the halves would match exactly.
No, my triangle does not have a line of symmetry. It cannot be folded anywhere to make the two halves match exactly.
