Given (2012-a) (2010-a) = 2009, find the value of (2012-a) ^ 2 + (2010-a)
Let x = (2012-a) y = (2010-a)
X^2+Y^2=(X-Y)^2+2XY=2^2+2*2009=4022

It is known that the triangle ABC takes a point P in the triangle as the position like center, and makes the figure def of the triangle ABC after being magnified twice, so that several shapes can be made
The answer is one, I think it's two, because for example, it can be extended in the direction of AP or PA, and I can draw it, please help me
2. There is only one resemblance center of two resemblance figures;
3. Two iconicity figures may be located on both sides of the iconicity center or on one side of the iconicity center;
Two triangles are one on the same side and the other on the other side. I also think it's two. It's wrong to say one!
It's two triangles with P points 180 ° to each other
It can only be one, because point P is a point in triangle ABC
It can only be one, because the graph made by "AP direction extension" is only similar, not identical. The identical graph needs the corresponding edge to be parallel or on a straight line, but it is not parallel

First, rotate a triangle ABC about point a by 60 degrees, and then translate it to the right by 2 units to get the triangle def. Then the following wrong conclusion is
A three corresponding edges are equal; B three corresponding edges are parallel; C three corresponding angles are equal; d the shapes and sizes of the two figures are the same
B
It's not parallel
B is wrong
b. I've learned this kind of problem, believe me, with exclusion
B

In square grid, angle 1 + 2 + 3 + 4 + 5=_____
A 3 × 3 square grid is connected from the lower left vertex of 1 column and 3 rows to the upper right vertex of the small square of 1 column and 1 row, 2 columns and 1 row, 3 columns and 1 row, 3 columns and 2 rows, 3 columns and 3 rows respectively, and the angles between each line and the right side of each small square are 1,2,3,4,5 respectively
Note: the answer is 225 degrees.
Angle 1 and angle 5 are congruent triangles, so ∠ 1 + ∠ 5 = 90 degrees. Similarly, angle 2 and angle 4 are congruent triangles, ∠ 2 + ∠ 4 = 90 degrees, ∠ 5 = 45 degrees, so the answer is 225 degrees
A fraction multiplied by a fraction is equal to 60, and the fractions should be the same

2√15/1
2 / 1 times 15 under the root
1/8*1/8=1/64
2√15/1
2 / 1 times 15 under the root
1/4*1/4*1/4=1/64
More than that
In the 4 × 4 square grid as shown in the figure, ∠ 1 + ∠ 2 + ∠ 3 + ∠ 4 + ∠ 5 + ∠ 6 + ∠ 7 = ()
A. 330°B. 315°C. 310°D. 320°
It can be seen from the figure that: ① the congruence of the triangle where the residual angles of ∠ 4 = 12 × 90 ° = 45 °, ② ∠ 1 + 7 = 90 ° is the same as ∠ 2 + 6 = 90 °, and ∠ 3 + 5 = 90 °
