# How can I shift an array further left?

I want to move an array about 3 or 4 cm further to the left. Knowing how to align it on the left side of the page could be useful too.

The code is:

\documentclass{article}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\section*{Question 10}
\begin{figure}[h!]
\includegraphics[width=\linewidth]{"D:/.../question 10".png}
\end{figure}
Let $K\hat{P}L = x$ and $K\hat{Q}M = y$. Required to prove: $\triangle KPL ||| \triangle KMQ$.
\linebreak
$\begin{array}{rll} & O\hat{M}Q=y & (\text{isoc.} \triangle, OQ=OM)\\ \Rightarrow \ & P\hat{O}M = 2y & (\text{ext.} \angle \triangle)\\ \Rightarrow \ & \text{reflex} \angle P\hat{O}M =360^{\circ}-2y & (\angle \text{'s around a point})\\ \Rightarrow \ & 2P\hat{L}M = 360^{\circ}-2y & (\angle \text{at cntr}= \times 2)\\ \Rightarrow \ & P\hat{L}M = 180^{\circ}-y\\ \Rightarrow \ & K\hat{L}P = y & (\angle \text{'s on st. line})\\ \end{array}$
So, in $\triangle KPL$ and $\triangle KMQ$
$\begin{array}{rll} 1. & \hat{K} \text{ is common}\\ 2. & K\hat{L}P=y=K\hat{Q}M\\ \vspace{4mm} \therefore & \triangle KPL ||| \triangle KMQ & (A.A.) \end{array}$
\end{document}


I want to align the second array further left.

The document looks like this:

Secondly, it seems as if the \vspace{2mm} command is not working. How can I get a bit more space in-between the last two lines?

Thirdly, why is the word "Let" and the word "So" not aligned?

You can use the missile flalign* to left align the equations.
\begin{flalign*}

You can align the parts using the & method of flalign* itself, but I left it as an exercise.
You can add the vertical space using \4mm] Let is indented so not aligned with So. Use \noindent. Code: \documentclass{article} \usepackage{graphicx} \usepackage{amsmath} \usepackage{amssymb} \begin{document} \section*{Question 10} \begin{figure}[h!] \includegraphics[width=0.2\linewidth]{example-image} \end{figure} \noindent Let K\hat{P}L = x and K\hat{Q}M = y. Required to prove: \triangle KPL ||| \triangle KMQ. \begin{flalign*} &\begin{array}{rll} & O\hat{M}Q=y & (\text{isoc.} \triangle, OQ=OM)\\ \Rightarrow \ & P\hat{O}M = 2y & (\text{ext.} \angle \triangle)\\ \Rightarrow \ & \text{reflex} \angle P\hat{O}M =360^{\circ}-2y & (\angle \text{'s around a point})\\ \Rightarrow \ & 2P\hat{L}M = 360^{\circ}-2y & (\angle \text{at cntr}= \times 2)\\ \Rightarrow \ & P\hat{L}M = 180^{\circ}-y\\ \Rightarrow \ & K\hat{L}P = y & (\angle \text{'s on st. line})\\ \end{array} & \end{flalign*} So, in \triangle KPL and \triangle KMQ \begin{flalign*} &\begin{array}{rll} 1. & \hat{K} \text{ is common}\\ 2. & K\hat{L}P=y=K\hat{Q}M\\[4mm] \therefore & \triangle KPL ||| \triangle KMQ & (A.A.) \end{array} & \end{flalign*} \end{document}  • Thank you, this is perfect. Can I confirm that \[ and  are not used inside flalign because flalign is already an equation environment? – ahorn Sep 24 '15 at 12:28
• @ahorn Yes. You shouldn't use $...$ inside flalign. – user11232 Sep 24 '15 at 12:39
• Of course you don't want the figure environment. – egreg Sep 24 '15 at 14:06
