Type the correct answer in each box. Spell all the words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s). Two shaded triangles are graphed in an x y plane. The vertices are as follows: first: A (8, 8), B (10, 4), and C (2, 6); second: A prime (6, negative 8), B (8, negative 4), and C (0, negative 6). We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of unit(s) and a across the -axis.
One can project that ∆ABC is congruent to ∆A′B′C′ through a translation of (x-2, y) unit(s) and a across the x-axis.
What triangle is indicated in the diagram?The triangle ABC is shown in the image attached. The coordinates of the triangle are A(8, 8), B(10, 4), C(2, 6), while the triangle A'B'C' is at A'(6, -8), B'(8, -4), C'(0, -6).
What is a transformation?A transformation refers to the movement of a point from its initial location to a new location.
What are the types of transformation?The types are:
rotation, translation, dilation and rotation.If a point O (x, y) is translated a units on the x axis and b units on the y axis, the new coordinate is O' (x+a, y+b).
If a point O (x, y) is reflected across the x axis, the new coordinate is O' (x, -y)
Therefore, if triangle ABC is translated -2 units on the x axis (2 units left), the new coordinates are A*(6, 8), B*(8, 4), C*(0, 6). If a reflection across the x axis is then done, the new coordinates are A'(6, -8), B'(8, -4), C'(0, -6).

why do streams deposit most of the sediment they are carrying when they reach a body of water
Answer:
Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.
Streams deposit most of the sediment they are carrying when they reach a body of water because the velocity of water slow down.
What is a stream?It should be noted that a stream means a body of water that flows with the bed and banks of the channel.
