Triangle ABC was dilated using the rule DO,4. Triangle A'B'C' is the result of the dilation. Point O is the center of dilation. Triangle A B C is dilated to create triangle A prime B prime C prime. The length of O B is three-fourths. What is OB'? 1.5 units 3 units 4.5 units 6 units

Respuesta :

If the length of OB was ³/₄, then the length of OB' after dilation is; Option B: 3 units.

  • Dilation of an object simply means enlarging or shrinking of the object by a scale factor.

  • Now, we are told that Triangle ABC was dilated to Triangle A'B'C' using the rule D₀,₄.

What this means is that it was enlarged by a scale factor of 4 with point O as the center of dilation.

  • Now, if the length of OB is 3/4, it means that the new dilated length is gotten from;

Scale factor = new dilated length OB'/(³/₄)

new dilated length OB' = ³/₄ × 4

new dilated length OB' = 3 units
