  • 1.

    Which of the following triangles are always the same?

    • IN.

      Right triangle

    • B.

      Blunt triangle

    • C.

      Equilateral triangle

    • D.

      Isoceles Trekant

    Correct answer
    C. Equal triangle

    Explanation
    Asaria -three corners are always the same because all three sides are the same and all three corners are the same.This means that if you have two equilateral triangles, you can scale one the other triangle.That is why all equilateral triangles are comparable.

    The sides of a triangle are 7.10 and 12. Find the length of the longest side of a similar triangle of which is the shortest page 21.

    • IN.

      12

    • B.

      21

    • C.

      30

    • D.

      36

    Correct answer
    D. 36

    Explanation
    In a similar triangle, the corresponding pages are proportional to find the length of the longest side of the comparable triangle, we can set a share using the lengths of the sides.

    Let X be the length of the longest side of the comparable triangle.

    Use the share:

    7/21 = 12/x

    Cross-multiplying:

    SS = 21 * 12

    Simplification:

    SS = 252

    Divides both sides by 7:

    x = 36

    That is why the length of the longest side of the comparable triangle is 36.

  • 3.

    I striveabc, hoekIN= 90º and angleB= 25º. of the pastDef,hoekE= 25º and angleF= 65º.Is the triangles comparable?

    • IN.

      Vals

    • B.

      Right

    Correct answer
    B. Where

    Explanation
    Yes, the triangles are the same., the triangles are similar.

    Assess this question:

  • 4.

    Two triangles are the same.If the relationship between perimeter is 5: 3, you must find the relationship between the corresponding pages.

    • IN.

      5: 3

    • B.

      15: 9

    • C.

      25: 9

    • D.

      1: 8

    Correct answer
    A. 5: 3

    Explanation
    If two triangles are the same, it means that their corresponding corners are the same and the relationship between their corresponding pages is the same.The sides of the triangles is also in proportion 5: 3. For is the ratio of the corresponding sides of the triangles 5: 3.

    Which of the following conditions are not sufficient to identify some congruent triangles?

    • IN.

      Three pairs of similar pages are proportional (SSS).

    • B.

      Two pairs of similar pages are proportional and their recorded corners are the same (sas).

    • C.

      Two pairs of similar pages are proportional and a few non-pinching corners are the same (SSA).

    • D.

      Two pairs of corners are an (aa).

    Correct answer
    C. Two pairs of similar pages are proportional and a few non-pinching corners are the same (SSA).

    Explanation
    The condition that is not sufficient to identify some congruent triangles is "two pairs of similar pages are proportional, and a few non-pinling corners are the same (SSA).", It is not enough to guarantee congruence between triangles.

    Assess this question:

  • 7.

    What is true with corners on similar triangles?

    • IN.

      Opposite corners are congruent.

    • B.

      Similar corners are congruent.

    • C.

      Similar corners are 90 degrees.

    • D.

      Similar corners are parallel

    Correct answer
    B. Similar corners are congruent.

    Explanation
    Similar corners are congruent in similar triangles..

  • 8.

    Surface of an equilateral triangle with side length A is the same:

    • IN.

      P/Kha

    • B.

      √3/4A

    • C.

      √3/4 a2

    • D.

      √2/3A

    Correct answer
    C. √3/4 a2

    Explanation
    The correct answer, √3/4 a^2, represents the formula to find the area of ​​an equilateral triangle.In this formula, "a" length of one side of the triangle represents.^2) gangs with the constant √3/4 to find the area.

    Assess this question:

  • 9.

    If the circumference of a triangle is 100 cm and the length of the two sides is 30 cm and 40 cm, the length of the third side will be:

    • IN.

      30

    • B.

      45

    • C.

      24

    • D.

      16

    Correct answer
    A. 30

    Explanation
    The circumference of a triangle is the sum of the length of all its sides.In this case the circumference is given as 100 cm.Page We draw the sum of the length of the two sides of the perimeter.So 100 - (30 + 40) = 30 cm.

    Assess this question:

  • 10.

    The height of an equilateral triangle on page 5 cm is:

    • IN.

      5 cm

    • B.

      6,66 cm

    • C.

      4,33 cm

    • D.

      2,44 cm

    Correct answer
    C. 4,33 cm

    Explanation
    The height of an equilateral triangle can be found using the H = (√3/2) * s, where H is the height and s is the length of one side.Get h = (√3/2) * 5 = 4.33 cm.Because is the correct answer 4.33 cm.
