You are given two pairs of triangles. For the first pair of triangles, each side and angle of one triangle is congruent to the corresponding side and angle of the other. You show that rigid motions can transform one triangle so that it matches up with the other. For the second pair of triangles, you show that rigid motions can transform one triangle so that each angle or side of one triangle matches exactly with a corresponding angle or side of the other triangle. What have you proved?

Answers

Options:

a) If corresponding pairs of sides and corresponding pairs of angles of two triangles are congruent, then the triangles can be matched up exactly using rigid motions.

b) If two triangles can be matched up exactly using rigid motions, then the corresponding pairs of sides and corresponding pairs of angles of the triangles are congruent.

c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

d) If corresponding pairs of sides and corresponding pairs of angles of two triangles are not congruent, then the triangles are not congruent.

Answer:

c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

Step-by-step explanation:

For both pairs of triangles, what you proved is how to use rigid motions (i.e. rigid transformations) to make congruent shapes.

When rigid transformation is applied to a shape, the image (i.e. result) of the transformation produces an exact shape (i.e. equal corresponding angles and corresponding sides), meaning that the side lengths and the angles of the preimage (before transformation) and the image (after transformation) is unaltered.

Option (c) is true

3. Find the measure of arc JK.
Hint - arc LK is a semi-circle!
Find JK

A) 90
B) 116
C) 128
D) 130

Answers

Answer:

Option C

Step-by-step explanation:

We will analyze the figure and note down the properties given in the figure,

1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.

m(arc LJK) = m(arc LK) = 180°

2). m(∠JKL) = 28°

Therefore, by the property inscribed angle and intercepted arcs,

Intercepted arc (JL) = 2 × (Inscribed angle JKL)

m(arc JL) = 2(26°)

= 52°

Now we will use these two points to get the measure of arc JK.

m(arc JK) + m(arc LK) + m(arc JL) = 360°

m(arc JK) + 180° + 52° = 360°

m(arc JK) = 360° - 232°

= 128°

Option C will be the correct option.

15 + x + 38 = 180

x + 53 = 180

x = 127

2x + 108 = 180

2x = 72
