Answer:
1). All four triangles are right-angled. 
3.) All four triangles are congruent. 
4) Area of a rhombus = 4 x area of one triangle. 
Step-by-step explanation:
If a rhombus is cut into four triangles using diagonals, the three statements that would apply to any rhombus would be that 'all those four triangles would be right-angled,' 'the triangles would be congruent to one another,' and 'area of one triangle * 4 would be equal to the area of the rhombus.' 
As we know, the diagonals bisect one another in a rhombus at 90° and the angles opposite to one another are equal. This <u>proves that all four triangles constructed through the diagonals would be ≅ through SSS congruency and perpendicular to one another because the corresponding edges of the congruent triangles are also ≅</u> . Since the rhombus is divided into four equal parts, the area of one triangle into four would be equals to the area of the rhombus. Thus, <u>options 1, 3, and 4</u> are the correct answers.

Answer:
Cherry Pink has not been made (
)
Step-by-step explanation:
Given that she already has 60litres of Rose Pink paint, we use the ratios to determine the volumes of red/white used:

#Add these proportions to the additional red and white paints to determine if Cherry Pink has been made:

We equate this proportion to the Cherry Pink proportion to verify if Cherry pink has been made:

Hence, Cherry pink has not been made.
